Overview
The C100H32EFM is a Schneider ComPacT NS new generation 3-pole molded case circuit breaker rated 1000 A at 50 °C with an 85 kA ICu breaking capacity at 690 V AC, fitted with a MicroLogic 2.0 E electronic trip unit providing L (long-time) and I (instantaneous) protection. It includes an LCD display and integrated energy meter, and is manually operated with a fixed mount and front connection surface.
Selection and sizing
Rated 1000 A continuous at 50 °C with an 85 kA ICu, this breaker is sized for high-fault distribution panels where the available fault current reaches 85 kA at 690 V AC — typical for industrial main feeders or large sub-distribution. The MicroLogic 2.0 E trip unit covers overload (L) and short-circuit (I) only; no ground-fault or selective protection is built in, so it suits radial distribution rather than zone-selective interlocking.
How it compares
Compared to the C160H32EFM, the C100H32EFM shares the same 3-pole frame and 85 kA ICu but is rated 1000 A versus 1600 A — pick the C160H32EFM when the load exceeds 1000 A or the BOM specifies a 1600 A frame.
