Schneider Electric EasyPact EZC250N - TMD - 250A - 3 Poles 3d MCCB

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.
