1.1 Functions performed by electricalswitchgear

National and international standards define the method for making electricaldistribution circuits as well as the purpose and functions of switchgear.There are three main functions, namely:n circuit protection takes three main fault types into account:o overloads,o short-circuits,both of which adversely affect the lifetime of cables and loads,o insulation faults, harmful for persons and equipment.n isolation is used to separate a circuit or a device from the remainder of theinstallation to allow 100% safe operation,n control allows the user to take voluntary action on installation operation:o when such action takes place in normal operating conditions (on load, with noovercurrent) in order to energise or de-energise all or part of the installation,control is said to be functional,o when such action is essential (whatever the load condition of the installation) inorder to immediately de-energise all or part of the installation, control is said to beof the emergency stop kind.

A variety of switchgear perform all or some of these three main functions. Thefollowing table situates the role of the main switchgear:

Three main functions:n protection,n isolation,n control,of electrical circuits.

The switch is used for:n control,n often isolation.

For protection it must becombined with:n a circuit-breaker,n fuses,n a residual current device(if necessary).

1.2 Functions performed by the switch

The switch is mainly:n a control device:o control is normally manual,o it can be electrical on opening (we then talk of a switch with automatic opening),o able to break and make a circuit on-load.It does not need any energy to remain open or closed (2 stable positions).n for safety reasons, the switch is often equipped with a suitability for isolationfunction,n the switch must always be used in coordination with an overload and short-circuit protection device.

Switches are characterised bymarket values taking into account:n 6 applications,n the installation method,n user habits such as type ofisolation: with visible isolation orpositive break indication.

These market values inducechoices of technology andreference standards.

2.1.1 Switch applicationsEntified, namely:n Power switchboard isolation and coupling switch:These switches are of the industrial type and are installed in power orsubdistribution switchboards in tertiary or industry. They comply with standard IEC60947-1,-3 (1). Suitability for isolation and a high thermal withstand (particularly forthe coupling function) are vital functions.

n Local or subdistribtion isolation switch for Tertiary Buildingapplications:These switches are of the industrial type and are installed in subdistributionswitchboards or industrial enclosures. They comply with standard IEC 60947-1,-3 (1)and can have a modular profile. Suitability for isolation and electrical data defined forutilization categories greater than or equal to AC 22 are vital functions.

n Local or subdistribtion isolation switch for Domestic Buildingapplications:These switches comply with standard IEC 60947-1,-3 (1) or IEC 60669-1(1). Suitabilityfor isolation is an essential function. Earth leakage protection is an additional functionthat is often requested.

n Local or subdistribution isolation switch for industrial applications ofthe Continuous Process type:These switches, of the industrial type, comply with standard IEC 60947-1,-3 (1) andcan have a modular profile. They can occasionally control motors and perform theemergency stop function. Suitability for isolation is an essential function.

Suitability for isolation is an essential function. In someutilisation cases they can perform:o the emergency stop function,o direct control of motors.

2.1.2 Market valuesAccording to its position in the installation, its application and assembly in theinstallation system, the switch must meet certain market values in terms of:n adaptability to installation systems,n standard requirements (installation).

Market values must also be considered, relating to habits such as:n operating handle types (front, side, etc.),n accessory level,n assembly habits,n visible isolation,or other habits linked to operator safety such as:n rapid identification of the isolation device in the middle of other devices,n robustness appearance of switchgear performing the on-load circuit control andisolation function,n etc.

The summary of applications and market values leads us to consider thefunctionalities listed in the table opposite.

(1) As from the beginning of 1998 IEC standards have received new numbering in IEC 60xxx.However their content remains the same.

2.2.1 Functions applicable to all switches2.2.1.1 StandardsTo satisfy the previous applications, two technologies are available:n industrial type switches for industrial and tertiary applications,n industrial type switches for domestic applications.

The reference standards for switches are:n in industry and the tertiary sector:o standards IEC 60947-1 and IEC 60947-3 / European standards EN 60947-1 andEN 60947-3.n in domestic applications:o standard IEC 60669-1.

2.2.1.2 IsolationOperation of an electrical installation requires the possibility of working with poweroff on all or part of this installation in order to perform maintenance and servicingor to make modifications.n Padlocking a feederInstallation standards define the compulsory feeder padlocking operations toguarantee safety of the operations. Switchgear separating the relevant feedermust be recognised as suitable for isolation and possess a locking system in the"open" position.n Position of isolation in the installationAn isolation device must be installed at the origin of each circuit distribution point inorder to ensure optimum continuity of supply ("incoming end" of the enclosure/subdistribution cubicle).

2.2.1.3 Switch/disconnectorSome switches perform this function in addition to their circuit control function.They are then switches/disconnectors whose symbol, shown opposite, must beclearly shown on the front face of the device installed.

Suitability for isolation is animportant function that the switchmust possess.

On-load breaking is a naturalfunction of the switch.

Figure 2: Marking a switch suitable for isolation

The isolation function is performed in 2 ways:n visible isolation,n positive break indication.The industrial switch construction standard IEC 60947-3 defines the rules and thetests to be performed to guarantee this function (see section 3.3.4).

7n Suitability for isolationIsolation is explicitly defined and recognised by standard IEC IEC 60947-1-3 forindustrial type switches/disconnectors. A switch/disconnector complying with thisstandard for the isolation function unconditionally meets the additional tests andrequirements of the installation standards.n Implementation and utilisation precautionsSwitchgear suitable for isolation must:o have multi-pole breaking, i.e. the live conductors, including the neutral(except for the PEN conductor that must never be broken) must be able to besimultaneously broken,o be lockable in the open position in order to avoid all risk of accidentalreclosing, essential on industrial type devices,o be able to meet overvoltage withstand conditions.Before working on the part of the installation downstream of a switch/disconnector, the user must:o open the switch,o then, in all cases, compulsorily check absence of power,(if the switch has visible isolation, see section 334 of the Standards - suitability forisolation),o check contact opening.n Choice of isolationChoice of isolation mode depends on:o market habits,o switch rating.The manufacturer must:o propose safe, reliable solutions guaranteeing customer safety,o ensure the best possible value (quality and performance) for money.n Comparison of the 2 isolation typesThe table below summarises the advantages and drawbacks of each solution.

Table B

2.2.1.4 On-load breakingThe operator must be able to safely and easily put his electrical installation out ofoperation regardless of load conditions. For switches, on-load breaking isessential and tests are required by standard IEC 60947-3. Switch electricalperformance depends on its position in electrical distribution:Type of current to be controlled:The utilization categories defined by standard IEC 60947-3 specify the variousrequirements to be met according to the circuits to be controlled.n When the switch is installed at a high upstream level in LV distribution, the loadssupplied are numerous and mixed: the current to be controlled is of the inductivetype. Utilization category AC22 is recommended for this type of switch.n When the switch is installed at the incoming end of the distribution enclosure (orcubicle), the loads supplied may be not very inductive (power supply, lighting,convector, etc.). Utilization category AC21 is sufficient for this type of application.However, the same type of enclosure can be used to supply a mixed installationwith motors: utilization category AC22 is then necessary. To simplify the choiceand guarantee proper operation, whatever application is performed, utilizationcategory AC22 is always recommended at this level.n When the switch is placed directly on a motor feeder and used as a controldevice, it must meet:o a utilization category AC23, if control is occasional (normal control by acontactor),o a specific utilization category AC3, if the switch is the main motor start-up andstopping device.

8Number of operationThe nearer the switch to the loads, the greater the number of operations. A suffixattached to the utilization category -A (frequent operations) or B (infrequentoperations) defines operation frequency. In electrical distribution, the number ofoperations to be performed is never very great (a few thousand).

2.2.1.5 Additional safety functionsAdditional functions are often requested for switches ensuring local andsubdistribution isolation.

n The emergency stop controlThis is performed in 2 ways:o remotely by an emergency pushbutton either by a contactor or by a switch withautomatic opening. The controlled switch is installed in a switchboard or enclosurein standard manner. It is necessarily equipped with an automatic tripping deviceand, in many cases, with auxiliary indicating contacts,o directly by means of a switch. Safety regulations and/or installation standardsspecify that in this case the device must be easy to identify and access.Identification is based on choice of colours:- operating device (red handle),- front face (yellow front plate).

n Insulation fault protectionInsulation fault protection can be provided by a Residual Current Device (RCD)associated with or incorporated into a switch depending on the application inquestion.o Subdistribution switchboard isolation switchThe RCD is associated with a controlled switch (with automatic tripping).The RCD provides protection of persons (indirect contacts) and protection againstfire. It must be selective with the downstream RCDs.o Final distribution switchboard and enclosure isolation switchThe RCD is built into the switch and is normally dedicated to a single protectionfunction: persons (direct contact), fire, etc.

NB: In all cases, the chosen switchgear will be able to break overloads andabnormal currents, thus excluding from this function devices only of thedisconnector type.

92.2.2 Specific functions2.2.2.1 The coupling functionDepending on the position of the switch in the LV installation and on the operatorsspecific needs, the coupling function can be automatic or manual.

Automatic couplingn This function is normally built into the source changeover function (e.g. 2sources and 1 coupling). Should one of the sources fail, the loads areautomatically coupled to the second source. This is performed at the supply end ofLV distribution.n This function is mainly found in the main LV switchboard or the incomers of thesubdistribution switchboard (see fig. 4a and 4b).n Specific featuresThe switches are located near the sources: the lsc are high (from 30 to 80 kA).Time discrimination is often used: the fault currents are not limited. This results in aneed for high withstand performance in short-circuit conditions:o thermal stress withstand: the main LV switchboard specifications may impose awithstand of 80 kA - 1s for a busbar in a 3000A main LV switchboard,o making capacity lcm: the coupling may close and make a high short-circuitcurrent.Switchgear has a motor mechanism. An electrical and mechanical interlocking withthe other source changeover switch components is necessary.NB: When this function is combined with the automatic source changeover function, it can beperformed by circuit-breakers with only instantaneous protection to limit stresses on theinstallation in event of closing on a short-circuit.

Manual couplingn This function is normally used to couple:q a set of loads on an emergency network,q a set of loads on a moving generator.The switch manually and locally performs the transfer to the emergencyreplacement network. This load transfer is occasional and programmed.n This function is mainly found on the incomers and feeders of the subdistributionswitchboards (see fig. 4c).n Features: switches are at the heart of distribution:q they are normally protected by limiting type circuit-breakers,q occasional, voluntary coupling considerably limits the risk of anomalies(particularly during coupling).The switch has standard features and is of the manual type. Device interlocking isnecessary.

2.2.2.2. The motor "isolation" functionWhen a motor circuit is supplied and protected from a centralised power supplyto guarantee safety and simplify maintenance, a local control and isolation deviceis frequently required. These functions are performed by a separate device knownas a local isolation enclosure containing an on-load breaking switch.

Switch featuresn In most cases, motor control is performed by a contactor. The switch onlyperforms occasional control of the motor: utilization category is AC23.

n For some small motors (< 18.5 kW), the switch may be considered to be the maincontrol device of the motor: utilisation category is AC3.

n Additional functions: the switch function is completed by locking in the openposition to ensure safe maintenance of the feeder. This switch can also be usedas an emergency stopping device (red front plate, yellow handle).

t

The switch must comply with:n standard IEC 60669-1 fordomestic applications,n standards IEC 60947-1 and60947-3 for tertiary and industrialapplications.

These standards specify the maintechnical data of the switches: ratedcurrents and voltages, utilisationcategory, etc.

Standard IEC 60947-3 completelydefines the suitability for isolationof industrial switches.

3.1 General

Low Voltage switchgear standards lay down all the general common and specificrequirements and measures. They particularly specify:n equipment definitions,n its technical data,n information on the equipment,n normal operating, assembly and transportation conditions,n construction and operating specifications,n tests.

The switches comply with standards(1):n IEC 60947-1 (general requirements) and IEC 60947-3 (specific switchrequirements) for industrial switches,n IEC 60699-1 for domestic switches.

3.2 Normal standard values for domesticswitches (IEC 60669-1)

n Rated voltages and currentso rated voltage: preferably 130 V, 230 V, 250 V, 277 V, 400 V, 415 V, 440 V,o rated current: preferably 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 63 A.

n Breaking capacityThe standard stipulates a suitable breaking capacity. This conformity is verifiedby a test depending on rated voltage and current as given below.Switch type Test characteristicsRated voltage Current voltage Test voltage Test currentUe Ie k1 x Ue k2 x Ie 250 V 16 A 1,1 1,25> 250 V > 16 A 1 1,2

Table EThe standard stipulates 200 breaks at cos = 0.3 with rates specified accordingto rated current.

nnnnn Normal operationSwitches must withstand the following number of operations, for their ratedvoltage and current:Rated voltage Rated current Operations 250 V 16 A 40 000> 250 V 16 A 20 000All voltages 16 A < Ie 40 A 10 000All voltages > 40 A 5 000

Table F

n Suitability for isolationStandard IEC 60699-1 does not give any recommendations regarding visibleisolation or positive break indication.

The tests required are also less demanding than for industrial switches:o for dielectric testing, a 50/60 Hz voltage of between 2000 V and 4000 V(depending on application point) is applied for 1 minute. A check is run to ensurethat the insulation resistor retains a minimum value (2 to 5 M according to thetest),o no impulse wave testing required.

Moreover, the domestic switch test conditions match class AC22, see section 3.3.3.

(1) IEC standards were renumbered in IEC 60xxx at the beginning of 1998, but their contentremains the same.

13

3.3. Normal standard values of industrialswitches (IEC 60947-3)

The specifications and tests relating to each switchgear type include 2documents:n the general requirements of standard IEC 60947-1,n the specific standard for the equipment considered.For switches, standard IEC 60947-3 completes, amends or replaces thespecifications of the general requirements of standard IEC 60947-1.

3.3.1 The definitionsThe standard gives specific definitions, including those for:n The switch: a mechanical connection device:o able to make, withstand and break currents in normal conditions, includingoverloads,o able to withstand currents in abnormal conditions, such as short-circuits, for aspecified period of time,o able to break on no-load (with no load downstream).

n The disconnector: a mechanical connection device:o meeting the specifications for the isolation function in the opening position,o able to withstand currents in normal conditions as well as currents in abnormalconditions, such as short-circuits, for a specified period of time.

n The switch/disconnector:o a switch meeting the specifications for the isolation function in the openingposition.

3.3.2 Standard usage valuesn Conventional thermal current, lth (A)The maximum current that a switch can permanently convey without excessivetemperature rise. This value is associated with a utilisation temperature given bythe manufacturer:e.g. lth = 400 A, lth = 25 A at 40C.Normally lth = lu (lu = unbroken current). lth actually corresponds to the switchrating.

n Short-circuit making capacity, lcm (A peak)The short-circuit current value that the switch can make, on closing on a short-circuit, without being damaged.

3.3.3 Utilization categoriesThe standard identifies three types of utilization categories:n AC21: resistive loads,n AC22: mixed loads,n AC23: inductive loads,n AC3: direct control of a single motor.

As regards DC current devices, categories are respectively: DC20, DC21,DC3, etc.

A letter, A or B, is associated with each ACxy category, according to whether ornot the device is designed for frequent switching operations:n A: frequent operations: from 2 000 to 10 000 operations (mechanical andelectrical) as per rating,n B: non frequent operations: from 400 to 2 000 operations (mechanical andelectrical) as per rating.

3.3.3.2 ExampleA switch with a rating of 125A and category AC23 must be able to:n make a current of 10 ln (1 250 A) with a cos of 0.35,n break a current of 8 ln (1 000 A) with a cos of 0.35.

3.3.4 Suitability for isolationStandard IEC 60947-1 clearly defines the general rules governing suitability forisolation.Standard IEC 60947-3 specifies the requirements to be respected to perform theswitch isolation function.These standards are based on:n the construction rules,n the tests to be performed.

3.3.4.1 The construction rulesThe construction rules stipulate (among others):n the clearances and the distances between open contacts (> 1mm/kV) or, if thisis not the case, verification by sampling device withstand to voltage impulses,n presence of a device indicating the real position of the contacts (operatinghandle if its position is representative of that of all the contacts),n when an interlocking position is provided, the setting in the interlocked positionmust be possible only if the contacts are open.

15

3.3.4.2 Visible isolation or isolation with positive breakindicationIsolation can be achieved in two ways:n visible isolation, in which the operator directly views, through a transparentscreen, the physical separation of the main contacts,n isolation with positive break indication: in this case a mechanical deviceguarantees that the position of the main contacts reflects the position of thehandle. In other words, the switch handle must only indicate the open position ifthe main contacts are effectively separated.The standard defines for this a mechanical verification test (the welded contacttest).The standard specifies that a switch suitable for isolation must be equipped withpadlocking of the isolated status.The interlocked position must only be possible when contacts are open.

3.3.4.3 Tests to be performed

(1) All electrical installations can be subjected to occasional overvoltages with many causessuch as:n lightning overvoltages,n switching overvoltages,n overvoltages due to a fault,n overvoltages further to an MV/LV flashover.The study of these overvoltages (origin, value, location, etc.) and the rules to be applied forprotection, form the elements of insulation coordination. These studies recorded in standarddocuments define the voltage level Uimp to be applied to a device to ensure that it guaranteesthe safety of the de-energised part.

Three specific tests must be performed:n Impulse wave withstand (Uimp)(1)Conditions are those defined by standard IEC 60947-1, i.e.:o either a distance between contacts greater than that given for a non-homogeneous field,o or the withstand to an impulse wave whose level is defined according to thevalue Uimp declared by the manufacturer.The impulse wave withstand tests (1.2/50 s wave), defined in IEC 60947-1, of avalue Uimp variable according to the place of installation, are representative oflightning and switching overvoltages. They must be performed by themanufacturer if he announces a value for Uimp.

The Schneider ElectricchoiceSchneider Electric offers switch ranges of the Merlin Gerin and Telemecaniquebrands. These devices cover all the requirements of Low Voltage electrical powerdistribution, namely:n industrial switch/disconnector ranges meeting standard IEC 60947-1-3 from 12to 6 300 A,n domestic switch/disconnector ranges meeting standard IEC 60669 from 1 to 125A and in some cases standard IEC 60947-3,n switch/disconnector ranges for motor feeders meeting standard IEC 60947-1-3from 12 to 175 A.

The ranges of switches proposed:n are perfectly coordinated with the Schneider Electric protection devices,n fit perfectly into the Schneider installation systems, thus optimising theirimplementation,n are suitable for isolation.

19

In sh

In its capacity as a manufacturer,Schneider Electric has chosen tocompletely guarantee operatorsafety by necessarily offeringswitches satisfying the isolationmode with positive break indication.

4.1 The Schneider Electric technicalchoices

4.1.1 IsolationCircuit isolation is a function that must be performed in complete safety.

4.1.1.1 Choice of isolationFor those ranges of switches, Schneider Electric has chosen :the isolation mode with positive contact indication.

To ensure maximum user safety, the isolation mode with positive contact indicationis the most effective solution from a technical standpoint. The position of thecontrol device guarantees absence of voltage.

4.1.1.2 Positive contact indicationn AdvantagesFor devices with positive contact indication, the position of the control device in therest position reflects contact opening.This function is:o guaranteed by the manufacturer (inherent safety guarantee) and is no longerthe operators responsibility,o possible whatever kind of accessories are used: extended handle, handlethrough door, etc.

n Implementation requirementsThere are no special requirements linked to use of this technology type. Withpositive contact indication, the position of the control device must reflect contactposition by means of a reliable and tamper-proof mechanical device, the tests forwhich are defined by standards.

Consequently, there is no longer any risk of incorrect judgement by the user, as isthe case for switches with visible isolation only.

4.1.1.3 Visible isolationVisible isolation is sometimes imposed by installation standards (in France, forexample, standards NF-C 13-100 and NF C 14-100 concerning connection).nnnnn AdvantagesVisible isolation appears to offer operators additional safety as they can observecontact opening.

nnnnn Implementation requirementsAs indicated page 9, before working on the installation part downstream of aswitch/disconnector, the user must:o open the switch,o then, in all cases, check absence of voltage. If the switch has visible isolation(refer to Standards - suitability for isolation) the user must :o check contact opening.

Isolation is in actual fact guaranteed by the operator who has validatedcontact opening.

Visibility is perfect when the device is new and mounted in an enclosure without adoor. For visibility to be guaranteed over time, a certain number of designrequirements are necessary.

20

The following table lists the phenomena that might interfere with contact positioninterpretation:

Application case ObservationsDevice status after electrical switching Current breaking pollutes the apertureoperations and visible isolation becomes

questionable and even invisible.Use of switch with an extended or For guaranteed isolation, it is necessaryside handle in an enclosure with to open the enclosure door to check thatplain door contacts are really separated.

Otherwise, there is a risk op padlockinga device that is not open.There is a real danger for the user (1).

Use of switch with an extended or It all depends on equipment assemblyside handle in an enclosure with and place of installation. The result maytransparent door may be very similar to the above case.

Table J(1) The standard does not impose mechanical tests on the interlocking linking the position of thehandle to that of the contacts for devices with visible isolation.

4.1.1.4 Schneider visible isolation technologySchneider Electric has developed a specific range of switches (INV range). Forthese switches with visible isolation, Schneider gives priority to maximumsafety:n isolation with positive contact indication is guaranteed in addition to visibleisolation,n the main switch contacts are placed at the rear of the device. Consequently, therange is optimised to offer the best compromise between user safety and visibilityof main contacts: class 2 classification of devices is maintained,n the transparent cover allowing contact visibility is guaranteed for 200 electricalswitching operations. Beyond this number, its interchangeability will allowmaintained visibility,n isolation with positive break indication is maintained.

Schneider has chosen to assume responsibility for the isolationfunction.

front faceclass II

Figure 10: Class II diagram

4.1.2 Front face class IIThe Schneider Electric devices are front face Class II: this Class is maintainedwhen the device is equipped with direct control via a metal front plate (case of aDevices must be designed according to specific building considerations:n case of devices with positive break indication. There are two insulatingenclosures (double insulation front face): safety is maximum,n case of devices with visible isolation. Class II is obtained by demanding criteriato be respected (for devices with an Ui 750/800 V):o impulse wave withstand at 14.7 kV,o backing up of creepage distances.These criteria have a certain effect on device construction, as devices with visibleisolation cannot have a double insulating barrier:- the main contacts are located at the rear of the switch to ensure maximumsafety,- visibility of main contacts is thus slightly less good, but user safety is maximum.

4.1.3 Emergency stop controlnnnnn By manual controlThe INS, INV and VARIO switch ranges, are also available in the emergency stopswitch version, conform to VDE recommendations.These switches can be identified by their colours: red handle, yellow case frontface.Switch characteristics and performance are identical to those of standardswitches.nnnnn By automatic controlThe switch is standard and trip-free. To perform a safety function, tripping will usean MN coil. This coil will be de-activated by the emergency stop normally closedcontact.

4.1.4 The switch is an environmentally-friendlyproductAnxious to protect the environment, Schneider Electric takes three types of action:n first, it produces products of a modular design and thus completely separableinto single-material components,n second, it uses:o materials containing no harmful substances, in particular no cadmium, mercuryor asbestos,o carefully selected thermoplastics for the moulded parts of the device. Eliminationof these materials, even by incineration, does not give off polluting substances.n third, it implements non-polluting manufacturing processes: ISO 14001certification of its products manufacturing sites.

Local isolation enclosuresEquipped with industrial switchgear for all ratings (up to 630 A) or with modularswitchgear for low ratings (up to 63 A).They are used to control and isolate machines and utilities locally (e.g. boiler plants,lift machinery).Applicable standard: IEC 60947-3.

Automation enclosuresThe current range for this application is normally limited to 40 A. The enclosure isfrequently built into the machine.The switches dedicated to this application are usually designed specifically for it(standard ratings: 16/25 A).This type of device normally includes many accessory possibilities (auxiliaryswitches, optional door mounting, etc.).Applicable standard: IEC 60947-3.

Small final distribution enclosuresAs a rule the incomer is a modular type device 63 A.Feeders are low rating Multi 9 circuit-breakers. All the devices are mounted in asmall modular enclosure.The choice of INS63 or l63 depends on the type of application:n INS63 for the commercial and tertiary sectors.Applicable standard: IEC 60947-3.n l63/ll00 for housing and domestic applications. It is often used as a direct controlswitch on final circuits (e.g. control of heating, convector, etc.).Applicable standard: IEC 60669-1.

4.2.2 Consistency of the circuit-breaker/switchranges4.2.2.1 Size and accessoriesAt power distribution level - 100 A to 630 A - it is essential for switch ranges to becompletely consistent with circuit-breaker ranges. Schneider Electric thus offersInterpact INS / INV ranges that are fully in line with the Compact NS circuit-breakerranges.Consistency is ensured for:n accessories (auxiliaries, rotary handle, etc.) shared by the 2 ranges,n dimensional features (pole pitch, physical size, etc.), particularly important,n design and colour.

This last option ensures rationalisation of the function:o by optimised size of switchgearo by implementation of a single 3-position rotary handle.This guarantees greater ease of mounting and safety of implementation.Consistency with the circuit-breaker ranges is respected thanks to identical fixingcentres and thus the same cabling gauge.A downstream coupling accessory completes the simplicity of the sourcechangeover switch function (the same for two switchgear).

4.3 Choosing a Schneider Electric switch

4.3.1 Choice criteria4.3.1.1 Network characteristicsNominal voltage, nominal frequency and nominal current are determined in thesame way as for a circuit-breaker:n nominal voltage = nominal voltage of the network,n frequency = network frequency,n nominal current = rated current of a value immediately higher than thedownstream load current. Note that the rated current is defined for a given ambienttemperature and that a derating may have to be taken into account.

4.3.1.2 Location and applicationThis determines the type and characteristics or main functions that the switchmust possess. There are 3 function levels (see table opposite):

nnnnn Basic functionsvirtually common to all switch types:o isolation, control, padlocking, safety.

nnnnn Additional characteristic functionso direct formulation of the needs of the user and of the switch environment, i.e.:- industrial type performance,- need for emergency stopping,- lsc level,- type of interlocking,- type of control,- utilisation category,- mounting system.

nnnnn Specific functionso linked to operation and to installation requirements, i.e.:- earth leakage protection,- motor mechanisms,- remote opening (emergency stop function),- withdrawability.The following table enables choice of switch according to requirements.

nnnnn Choice tableComparison of the application table ( 4.3.2) and the switch technical data table( 4.3.4) lets you specify which switch range should be used.

4.3.1.3 CoordinationAll switches must be protected by an overcurrent protection device placedupstream.

The "additional technical information" tables below give the SCPD (circuit-breakeror fuse) guaranteeing proper coordination with switches in event of adownstream short-circuit, according to the electrodynamic withstand or the short-circuit making capacity of the device.
