Schneider Electric C080N42AFM ComPacT NS800N 4P 800 A 50 kA MicroLogic 2.0 A Moulded Case Circuit Breaker

C080N42AFM is Schneider Electric's 4-pole ComPacT NS800N moulded case circuit breaker, rated 800 A with 50 kA Icu at 380/415 V AC. Its MicroLogic 2.0 A trip unit provides overload (long-time, L) and short-circuit (instantaneous, I) protection; the breaker is fixed-mounted, front-connected at both ends, and rated for 690 V AC operation. It also adds an integrated LCD ammeter for local current readout.

Selection Notes

The MicroLogic 2.0 A trip unit on the C080N42AFM 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 NS800 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 ammeter if local current readout isn't needed, while the E-suffix version swaps it for an energy meter. 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.
