The Schneider Electric EZC250H3160 is a 3-pole molded case circuit breaker from the EasyPact EZC250H series, rated 160 A at 40 °C with a TM-D thermal-magnetic trip unit. It provides short-circuit and overload protection for distribution applications, with a breaking capacity of 36 kA Icu at 400...415 V AC 50/60 Hz per IEC 60947-2. The H breaking capacity code means it handles higher fault currents than the standard S or N variants in the same frame, making it suitable for main or sub-feed protection where available fault current exceeds 25 kA.
The 160 A trip unit rating at 50 °C and 160 A rated current at 40 °C define the continuous load it can carry without nuisance tripping. Breaking capacity varies by voltage: 85 kA Icu at 240 V AC, 36 kA at 400 V, 25 kA at 440 V, and 10 kA at 550 V AC. On DC systems, it delivers 30 kA Icu at 125 V DC (1-pole) or 250 V DC (2-pole). The IP20 finger-safe enclosure and IK07 impact resistance protect against accidental contact and light mechanical shock during panel maintenance.
Fixed backplate mounting with front-connect terminals — both line and load connections are on the front face, so the breaker can be installed in a panel without rear-access buswork. Toggle control with positive contact indication gives a clear visual of contact state, useful during lockout/tagout.
