The Schneider Electric EZC100H4032 is a 4-pole molded case circuit breaker from the EasyPact EZC100H range, rated 32 A at 40 °C with a thermal-magnetic TM-D trip unit. The 'H' breaking capacity code means it delivers 100 kA Icu at 110-130 V AC, 50 kA at 220-240 V AC, 30 kA at 380-400 V AC, and 20 kA at 440 V AC — figures that govern its use in high-fault distribution panels where SCCR coordination is critical. At 125 V DC (1P) and 250 V DC (2P) it still holds 10 kA Icu, so it handles DC bus applications in the same footprint. The 32 A rating at 50 °C on the trip unit means you get the full 32 A continuous without derating up to that ambient — above that, the thermal element starts to shift. Mounting is fixed backplate, not DIN rail — plan for a dedicated cutout or enclosure backplate. Front connections both top and bottom simplify bus-bar routing in a distribution board. The 25 mm connection pitch matches standard MCCB terminal spacing for lug or fork terminals.
The EZC100H4032 is certified to EN/IEC 60947-2 (the main MCCB standard for industrial applications), EN/IEC 60947-1 (general rules), plus GB/T 14048.2 (China) and JIS C8201-2-2 (Japan). IP20 finger protection on the front face, IK07 impact resistance per EN 50102. Storage temperature range -35 to 85 °C, operating -25 to 70 °C — wide enough for unheated warehouses or outdoor enclosures in temperate climates.
