The Schneider Electric EZCV250N44225 is a 4-pole EasyPact EZCV250N molded case circuit breaker rated 225 A at 40 °C, fitted with a TM-D thermal-magnetic trip unit and integral earth-leakage protection. It carries a 20 kA Icu breaking capacity at 440 V AC (50/60 Hz) per IEC 60947-2, with higher ratings of 25 kA at 380–415 V and 85 kA at 220–240 V. The front-connect design and backplate mounting suit fixed-installation distribution panels where a compact 140 mm wide footprint is needed.
Pollution degree 3 (IEC 60947) means the internal clearances tolerate conductive dust typical of industrial enclosures — no additional derating for a dirty panel environment. The 10,000-cycle mechanical endurance sets the expected service life under normal switching; for frequent motor-starting duty, a contactor would be paired upstream.
Mounting and wiring integration
Backplate-mounted with a 35 mm connection pitch. Front-connect terminals on both line and load sides simplify bus-bar takeoff in a fixed-distribution panel. The IP20 finger-safe enclosure and IK07 impact resistance protect against accidental contact and light mechanical shock during panel wiring. Positive contact indication on the toggle provides a visual confirmation of the main contact state — no auxiliary contacts needed for a local open/closed check.
