The Schneider Electric EZCV250H4125 is a 4-pole molded case circuit breaker from the EasyPact EZCV250H series, rated 125 A at 40 °C with a TM-D thermal-magnetic trip unit. It carries a 100 kA Icu breaking capacity at 220...240 V AC and 25 kA Icu at 440 V AC, certified to IEC 60947-2. The integrated earth-leakage protection module makes it a single-enclosure solution for distribution panels where both overcurrent and ground-fault protection are required on the same outgoing feeder.
The H breaking capacity code delivers 100 kA Icu at 220...240 V AC, 36 kA at 380...415 V AC, and 25 kA at 440 V AC — all at 50/60 Hz per IEC 60947-2.
The 140 mm width and 165 mm height fit standard distribution panel cutouts; the 68 mm depth leaves clearance for rear-access wiring in enclosures with limited gutter space. The 35 mm connection pitch accepts standard busbar or cable lugs. IP20 finger-safe protection on the front face; IK07 impact resistance covers accidental tool drops during panel servicing.
Protection and isolation
Earth-leakage protection is integrated, so no external RCCB or RCBO is needed on the load side for ground-fault detection.
