The Schneider Electric EZC100H2080 is a 2-pole thermal-magnetic circuit breaker from the EasyPact EZC100H series, rated 80 A at 40 °C (80 A at 50 °C with the TM-D trip unit). It's built for distribution duty — Category A utilization, meaning it's not intended for frequent switching under load but for branch-circuit protection where the load is switched elsewhere. Breaking capacity varies by voltage: 100 kA Icu at 110–130 V AC, 50 kA at 220–240 V AC, 30 kA at 380–415 V AC, 20 kA at 440 V AC, 10 kA at 550 V AC, and 10 kA at 125 V DC (1P) or 250 V DC (2P). That H breaking-capacity code means it handles high fault currents on the low-voltage side of a transformer or near a large service entrance.
Fixed mounting on a backplate — no DIN rail adapter on this one. Front connections top and bottom, with a 25 mm connection pitch. Dimensions: 130 mm high, 50 mm wide, 60 mm deep. IP20 finger-safe terminals, IK07 impact resistance. Mechanical durability is 13,000 cycles — fine for a panel main or feeder breaker that sees infrequent operation.
