The Schneider Electric EZC100H1020 is a 1-pole EasyPact EZC100H thermal-magnetic circuit breaker rated 20 A at 40 °C, with a TM-D trip unit providing both short-circuit and overload protection. The 20 A rating at 50 °C tells you the breaker can carry its full load in a warmer panel — useful if the enclosure runs hot from adjacent devices. Breaking capacity is 25 kA Icu at 220...240 V AC, which means it can safely interrupt a fault current up to 25,000 A at typical North American line voltage without welding its contacts or rupturing. The part carries a Category A utilization rating, meaning it is not intended for current-limiting duty under short-circuit conditions; it simply clears the fault within its rated Icu. The single pole protects one phase, and there is no neutral or earth-leakage protection built in. Mechanical durability is rated at 13,000 cycles — fine for distribution panels where the breaker is operated infrequently, but not a motor-starting duty cycle.
Deployment context
This breaker mounts fixed to a backplate with front-side connections — typical for panelboard or distribution board integration. The 25 mm width and 60 mm depth fit standard modular spacing; the 25 mm connection pitch aligns with common busbar systems.
