The Schneider Electric EZCV250H44150 is a 4-pole EasyPact EZCV250H moulded-case circuit breaker (MCCB) rated 150 A at 40 °C, with a thermal-magnetic TM-D trip unit that provides overload, short-circuit, and earth-leakage protection in a single device. At 440 V AC the breaking capacity drops to 25 kA Icu, still adequate for typical 440 V line-side faults. The 4T protected poles cover all four poles with overload and short-circuit sensing; the neutral pole is unprotected.
It is rated IP20 (finger-safe) and IK07 (impact-resistant), so it suits installation inside a distribution enclosure where personnel do not contact live parts. Pollution degree 3 per IEC 60947 means it can operate in an industrial environment with conductive pollution.
