Schneider Electric C100N35EFM ComPacT NS1000N 3P 1000 A 50 kA MicroLogic 5.0 E Moulded Case Circuit Breaker

Rated 1000 A with a 50 kA breaking capacity at 380/415 V AC, the C100N35EFM is a 3-pole ComPacT NS1000N moulded case circuit breaker from Schneider Electric. The MicroLogic 5.0 E trip unit delivers overload (L), short-time delayed short-circuit (S) and instantaneous (I) protection, and the device mounts fixed with front connections rated 690 V AC. It also adds an integrated LCD energy meter for local readout.

Selection Notes

The MicroLogic 5.0 E trip unit on the C100N35EFM is configured for overload (L), short-time delayed short-circuit (S) and instantaneous (I) protection. Adding the S (short-time delay) stage to L-I lets this trip unit hold off tripping briefly on a downstream fault, so an upstream breaker can coordinate selectively with devices further down the circuit. 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 3-pole unit it protects the three phases only; the 4-pole version of the same frame adds switched or protected neutral handling.
