Easy series EasyPact™ EZC
Molded-Case Circuit Breakers from 15 to 630A
So easy, so simple
With just three sizes of circuit breakers, Schneider Electric's EasyPactTM EZC system is the simple, universal solution to fit all low voltage protection needs.
The fixed version is particularly adapted to the OEM and Building markets, offering optimum performance at a competitive price.
The plug-in version offers an additional function dedicated to the Marine market.
Earth-leakage protection
EasyPact EZC circuit breakers have a specific version including earth-leakage protection.
This protection is fully integrated inside the breaker and does not require any additional space.
EasyPact EZC circuit breakers and earth leakage circuit breakers are fully interchangeable.
Compliance with standards
EasyPact EZC earth leakage circuit breakers comply with all the international standards.
- IEC 60947-1
- IEC 60947-2
- EN 60947-1
- EN 60947-2
- GB 14048.2
- JIS C8201-2-2 Annex 1 and Annex 2
- UL 60947-4-1(old UL508)/CSA 22-2 no. 14.
They also comply with:
- VDE 664, operation down to -25 °C
- IEC 60255-4 and IEC 60801-2 to 60801-5 covering protection against nuisance tripping due to transient overvoltages, lightning strikes, switching of devices on the distribution system, electrostatic discharges, radiofrequency interference.
Power supply
Reverse feeding
EasyPact EZC earth-leakage circuit breakers can be supplied from either the top or the bottom for voltages up to 240 V AC. For voltages over 240 V AC, only supply from the top is possible (Line-Load indication on the cover of the breaker).
Power supply of the electronics
EasyPact EZC earth-leakage circuit breakers are self-supplied by the distribution-system voltage and therefore do not require any external source. They fully comply with new IEC requirements (Annex B): they are powered from the three phases and continue to function even if one phase is missing.
Dielectric tests
EasyPact EZC earth-leakage circuit breakers are equipped with a disconnecting switch in order to protect the electronics during dielectric tests.
When the disconnecting switch is activated, the circuit breaker is automatically tripped. It is mechanically impossible to switch on the circuit breaker, until the earth-leakage function is re energised.
Tripping features
Tripping indications:
- EasyPact EZC earth-leakage circuit breakers have a yellow mechanical indicator to locally signal tripping due to an earth fault.
- EasyPact EZC earth-leakage circuit breakers may be equipped with anearth-leakage alarm switch (ALV) to remotely signal tripping due to an earth fault.
Resetting
EasyPact EZC earth-leakage circuit breakers are fully reset by the operating handle.
After resetting, tripping indicators (mechanical and ALV) come to normal position.
