Molded case circuit breaker for distribution panels
The Schneider Electric EZC250H44150 is a 4-pole molded case circuit breaker from the EasyPact EZC250H series, rated 150 A at 40 °C with a TM-D thermal-magnetic trip unit. The toggle control gives positive contact indication — no guessing whether it's open or closed. At 380–415 V it handles 36 kA, and at 220–240 V it jumps to 85 kA, so the real limit depends on your system voltage. The IP20 finger-safe enclosure keeps hands out but doesn't seal against water; this is a panel-mounted breaker, not a standalone outdoor unit.
The breaker carries approvals under EN/IEC 60947-1 and EN/IEC 60947-2, the core standards for low-voltage switchgear and circuit breakers. It also meets JIS C8201-2-2 and GB/T 14048.2, covering Japanese and Chinese markets. IK07 impact resistance handles light mechanical shocks during panel assembly.
Mechanical durability and environmental range
Rated for 10,000 mechanical cycles — that's the expected life of the switching mechanism under normal operation, not the electrical endurance at full rated current. The 60 mm depth and 140 mm width fit standard backplate layouts; connection pitch is 35 mm for busbar or cable lug spacing.
