V-type locking system movements

Raise the levers until the locking block is released. Insert the mobile connector until it comes into full contactwith the fixed part.

Push the levers down and keep them outside the pegs on the hood.

Raise the levers and turn them so that the ends are abovethe pegs on the hood.

Remove the mobile connector from the fixed connector. Lower the levers until the locking mechanism isreleased.

A feature of the V-type locking system is that in the final locking stage the levers work by pressing down vertically on top of the hood pegs thus mini-mizing friction and wear and tear. The latch blocks on the enclosure pins that the levers are hinged to prevent the levers from being accidentally releasedeven if subjected to particularly heavy stresses.

description

standard version

This series has been developed for applicationin electric and electronic machinery, controlunits, electric panels, control equipment, indus-trial environments, and whenever a discon-nectable and reliable connection is required forpower and signal circuits.

Changeover from Pg threads to M metric threads

After 31st December 1999, the German safetystandard DIN VDE 0619 (1987-09) and the stan-dards it refers to - DIN 46319 for dimensions withmetric threads and DIN 46320 (T1-T4), DIN46255 and DIN 46259 for dimensions with Pgthreads (Panzerrohr-Gewinde=literally “steel con-duit threads” — were withdrawn and since 1January 2000 the European standard EN 50262“Metric cable glands for electrical installations”has been in force”. This standard defines the newsizes with metric threads for cable glands inaccordance with EN 60423 and establishes thesafety prescriptions. However, it does not specifythe dimensions such as the size of the tighteningwrench, the diagonal dimensions or the dimen-sions of the seal gaskets as was the case in thewithdrawn DIN standards for Pg cable glands. The standard came definitively into force on 1April 2001, when the conflicting national stan-dards were withdrawn. It is valid in all CENELEC(the European Committee for ElectrotechnicalStandardization) member countries and its publi-cation has led to an extension of the range ofenclosures for multipole connectors for industrialuse to include new enclosure versions with cableentries that are suitable for metric cable glands.Cable gland manufacturers have introduced thenew metric series alongside the Pg size seriesthat is will gradually replace. The transition periodindicated in the new standard should have endedon 1 March 2001 after which the use of Pg cableentry devices and, as a result, enclosures with Pgthreads, should no longer be used in new installa-tions. However, both the cable entry devices andenclosures with Pg threading, may continue to beused as spare parts. For the CE marking of theseitems, the safety conditions specified in the LowVoltage Directive must be observed. To distin-guish mobile and fixed surface mounting housingswith metric outlets from the Pg versions (markedwith a C pre-code), the ILME metric types aremarked with an M pre-code. The transposition table below indicates the corre-spondence rule adopted in most cases by ILMEfor creating the new metric versions.

conductor connections

description description description

contacts with screw terminals connections contacts with spring connection terminalswith wire protection

The different types of conductor connections to themale and female inserts are described on the right. The types can be summarised as follows:

- screw terminals- spring connection terminals

N.B.: for all inserts with screw terminals it is importantthat the right torsional torque is applied to thescrews in order to prevent faulty contacts or dam-age to the conductor, screw or terminal.

inserts: CNE

The conductors are connected to the female and maleinsert contacts by screws (in accordance with EN60999-1 standard).

inserts: CSE

The conductors are connected to the male and femaleinsert contacts by spring terminals.This type of connection offers the following advan-tages:- no special preparation of the conductors is required- a 3.5 mm x 0.5 mm blade screw-driver is all that is

needed for inserting the conductor into the contact - an excellent degree of clamping is obtained with high

resistance to strong vibrations- flexible and non-flexible conductors may be used

with cable sections ranging from 0.14 mm to 2.5 mm2

- conductivity tests may be performed under loadthrough the screwdriver opening without disconnect-ing the insert

- preparation and insert cabling times are considerablyreduced

phase 1

insertion of the screwdriver into thesquare slot opens the base of theconductor obtained within thespring.

phase 2

deep insertion of the conductor inthe round base.

phase 3

extraction of the screwdriver deter-mines the retention of the springon the inserted conductor.

phase 4

once the connection is complete, apulling action is to be applied totest the conductor’s retainingstrenght.

with plate

The CNE...T versions have a plastic cover that isused to guide the conductors into the contacts.

insert load curves

load curves

The current carrying capacity possible in the connectors is variable. It reduces with the increase of the number of polesand the temperature of the environment in which the connector is installed and is determined by the thermal proper-ties of the materials used for the contacts and the insulating parts as well as by the type of conductor used.The current carrying capacity is obtained from the load curves which are constructed according to standard IEC60512-3 for currents circulating simultaneously in all poles.The limit current curves express current values that determine the achievement of the highest limit temperature of thematerials. The choice of the permanent load applicable on the contacts must be made within the field of operationpossible delimited by the above curves.Since the use of the connectors at the limit of the values of their characteristics is not recommended, the base curveis derated. The reduction of the load curves to 80% defines the correction curve where both the maximum contactresistance permissible and the inaccuracy of the temperature measurements are sufficiently borne in consideration.The correction curve represents the final limit current curve (load curve) as defined by standard IEC 60512-3. It therefore bears in consideration the difference between the various connectors, as well as errors in the temperatu-re measurements.All the load curves presented herebelow include the corrections.

Legend:

Maximum load current (A): value for which the connector reaches the limit temperature of the material at the envi-ronmental temperature, intersected on the load curve.Limit temperature of the materials: value determined by the characteristics of the materials used. The sum ofthe environmental temperature and the increase of the simbolo ΔT temperature caused by the passage of the cur-rent must not exceed the limit temperature of the materials.Environment temperature limit: the environmental conditions must not exceed this value. It may be know anddetermines the maximum load current, or may be obtained directly from the load curve.Base curve: set of current and temperature values obtained from laboratory tests and influenced by the connec-tor’s characteristics (number of poles, construction shape, thermal conductivity of the materials, etc.) and the sec-tion of the conductor used.Load curve (limit current curve): obtained from the base curve via the safety coefficient.ΔT (overtemperature): temperature increase produced by a permanent current circulating through all the poles ofa connector coupling; difference between the limit temperature of the materials and the environmental temperatu-re obtained on the limit current curve.
