Schneider Electric EZCV250H4125 EasyPact EZCV250H 4P 125 A 36 kA TM-D Moulded Case Circuit Breaker

The Schneider Electric EZCV250H4125 is a 125 A EasyPact EZCV250H moulded case circuit breaker with integrated earth-leakage (Vigi) protection for low-voltage distribution. Its TM-D thermal-magnetic trip unit combines overload, short-circuit and earth-fault tripping, and the 4-pole frame breaks 36 kA at 380/415 V AC under IEC 60947-2.

Selection Notes

EZCV250H4125 folds earth-fault detection into the breaker itself rather than requiring a separate add-on Vigi module, so it suits a 4-pole distribution circuit that needs earth-leakage protection in the same DIN footprint as a standard EZCV250H breaker. The 125 A TM-D trip is fixed-thermal, so pick a different amperage in the EZCV250H4xxx line rather than relying on field adjustment if the protected circuit's load current changes. Because the 36 kA breaking figure applies at 380/415 V, verify prospective fault current at the installation point before using the 25 kA rating that applies at 440 V.
