Schneider Electric C100N42EFM ComPacT NS1000N 4P 1000 A 50 kA MicroLogic 2.0 E Moulded Case Circuit Breaker

Schneider Electric's C100N42EFM is a 4-pole, 1000 A ComPacT NS1000N moulded case circuit breaker with a 50 kA Icu rating at 380/415 V AC and a 690 V AC operational voltage. The fixed, front-connected breaker uses the MicroLogic 2.0 E trip unit for overload (long-time, L) and short-circuit (instantaneous, I) protection. It also adds an integrated LCD energy meter for local readout.

Selection Notes

The MicroLogic 2.0 E trip unit on the C100N42EFM is configured for overload (long-time, L) and short-circuit (instantaneous, I) protection. The L-I combination covers overload and instantaneous short-circuit tripping only, with no short-time delay stage. In the NS1000 case size, this N-frame breaker is the standard breaking capacity option (50 kA Icu at 380/415 V AC); the H-frame (70 kA Icu) and the L-frame (150 kA Icu) versions share the same case and accessories but trade breaking capacity for cost or vice versa. Within the same frame, the plain (no-suffix) trip unit drops the display, while the A-suffix version reads current instead of energy. As a 4-pole unit it supports neutral protection options (no protection, half-rated N/2, or full-rated 4D) rather than the fixed 3-pole configuration.
