The Schneider Electric EZCV250H4080 is a 4-pole molded case circuit breaker from the EasyPact EZCV250H series, rated 80 A at 40 °C with a thermal-magnetic TM-D trip unit. At 440 V AC the Icu drops to 25 kA, still adequate for most distribution boards on 400 V three-phase networks.
Fixed backplate mounting with a 35 mm connection pitch between poles. The 140 mm width and 165 mm height fit standard distribution board cutouts for 250 A frame MCCBs. IP20 finger-safe terminals and IK07 impact resistance mean the breaker can be installed in accessible enclosures without additional shrouding. The toggle handle provides positive contact indication (ON/OFF visible on the front face), which speeds fault isolation for a field service tech tracing a tripped circuit.
Protection and compliance
The TM-D trip unit combines thermal overload protection (inverse-time curve) with magnetic short-circuit protection (fixed instantaneous threshold). Earth-leakage protection is integrated — no external RCCB or Vigi module needed for ground-fault detection on the outgoing circuit. Standards coverage includes EN/IEC 60947-2, GB/T 14048.2, and JIS C8201-2-2, covering European, Chinese, and Japanese installation codes.
