Schneider Electric C080H460FM ComPacT NS800H 4P 800 A 70 kA MicroLogic 6.0 Moulded Case Circuit Breaker

C080H460FM is Schneider Electric's 4-pole ComPacT NS800H moulded case circuit breaker, rated 800 A with 70 kA Icu at 380/415 V AC. Its MicroLogic 6.0 trip unit provides overload (L), short-time delayed short-circuit (S), instantaneous (I) and ground-fault (G) protection; the breaker is fixed-mounted, front-connected at both ends, and rated for 690 V AC operation.

Selection Notes

The MicroLogic 6.0 trip unit on the C080H460FM is configured for overload (L), short-time delayed short-circuit (S), instantaneous (I) and ground-fault (G) protection. Stacking G (ground-fault) on top of L-S-I gives this trip unit adjustable earth-fault tripping as well as time-graded short-circuit discrimination, useful on solidly grounded systems that would otherwise need a separate earth-fault relay. In the NS800 case size, this H-frame breaker is the high breaking capacity option (70 kA Icu at 380/415 V AC); the L-frame (150 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 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.
