Schneider Electric C080L350FM ComPacT NS800L 3P 800 A 150 kA MicroLogic 5.0 Moulded Case Circuit Breaker

The Schneider Electric C080L350FM is a 3-pole ComPacT NS800L moulded case circuit breaker rated 800 A, with a 150 kA breaking capacity (Icu) at 380/415 V AC and a 690 V AC operational voltage. It carries the MicroLogic 5.0 trip unit for overload (L), short-time delayed short-circuit (S) and instantaneous (I) protection, and mounts fixed with front-connected upstream and downstream terminals.

Selection Notes

The MicroLogic 5.0 trip unit on the C080L350FM 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 NS800 case size, this L-frame breaker is the very high breaking capacity option (150 kA Icu at 380/415 V AC); the H-frame (70 kA Icu) and the N-frame (50 kA Icu) versions share the same case and accessories but trade breaking capacity for cost or vice versa. The A- and E-suffix trip units in the same frame add an ammeter or energy meter respectively, for installations that want local metering without extra hardware. 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.
