Overload Relays

• What is the Difference:

Between A Short Circuit & An Overload ?


Overload Relays

• What Is A Short Circuit?

– An Extreme Amount Of Current Usually Caused By A Fault To Another Phase Or To Ground.

– Fault Currents Can Exceed Several Thousand Amps For A Very Short Period Of Time Which Can Cause Very Extensive Equipment Damage. Fault Currents May Even Reach Up To 200,000 Amps On Some Systems.


Overload Relays

• What Is An Overload?

– 1. An Operating Condition Where The Load Current Exceeds Normal Operation.

– 2. A Motor That Is Overloaded May Draw 6 Times Its Normal Operating Current (Full Load Current).

– 3. An Overload For Even Several Minutes May Cause Severe Motor Damage.


Overload Relays

• What Are The Differences Between …

• A Fuse Or A Circuit Breaker And An Overload Relay?


Overload Relays

• Short Circuit Protection Devices– Fuses - One Time Use Only – Magnetic Circuit Breakers - Reusable After

Reset

• Overload Protection Devices– Time Delay Fuses -One Time Use Only – Overload Relays - Able To Reset

– Thermal Magnetic Circuit Breakers - Also Able To Reset

ESP100 Electronic OLR

• True phase loss protection

• Overload trips within 3 seconds on phase loss, even on lightly loaded motors (60% of minimum dial setting)

• Customer Benefit: Saves Motors!!!

• Thermal overloads just can’t provide this degree of protection


Electronic OLR

• Heaterless Construction– No heaters to install, stock, or maintain

• Customer Benefit: – Heaters require time and labor to install


ESP

• Self - Powered– Generates its own low voltage control power

through the same sensors that read motor current

• Customer Benefit: – Separate 120VAC control power is not

required


ESP100 OLR

• Ambient Insensitive– Overload not affected by temperature, rated -

30 °C to 70 °C

• Customer Benefit: – No nuisance tripping on hot days. No open

panel doors with fans blowing on controls.


ESP100 OLR

• 99% of heat generated by thermal overload removed

• Customer Benefit: – Other electronic equipment in panel runs

cooler, energy savings. More equipment could go into panel due to lower heat rise.


ESP100 OLR

• Energy Savings– Thermal overloads generate 9 to 24 watts per

relay– Based on 10 watts per overload and $0.10

per kW/hr, ESP100 will save $7.88 per year in energy costs

• This can really be significant if user has hundreds of starters!!!


ESP100 ORL

• Self protected from short circuits– Upon the event of a short circuit, the current

transformers saturate before any damage is done to the overload

• Customer Benefit: – No need to replace overload relay or heater

elements after a short circuit as is required with thermal overloads


ESP100 OLR

• ± 2 % repeat accuracy

• Customer Benefit: – Under the same conditions, trip time on the

overload will be the same within ± 2%


ESP100 OLR

• Circuit boards have conformal coating on them.

• Customer Benefit: – Rugged design that will hold up in humid,

corrosive environments


ESP100 OLR

• No two labels are the same – Every ESP100 overload is individually

calibrated and a custom label is printed for that overload.

• Customer Benefit: – Superior accuracy of dial setting - no

competitor does this!


ESP100 OLR

• Thermal Memory – “Remembers” the heat buildup in hot or

overloaded motors

• Customer Benefit: – Trips faster on a restart since the motor

windings are hot


ESP100 OLR

• Simple Installation – Mount it, wire it, dial in FLA

• Customer Benefit – Fewer connections, saves installation time


ESP100 OLR

• Retrofit Capabilities– Direct Replacement for:

• Cutler Hammer Citation Line and Freedom Series• GE 300 Line• Square D Type S

– An additional “piggy-back” plate is available to retrofit the following:

• Allen Bradley Bulletin 509 and Bulletin 709• Westinghouse Series A200
