Schneider Electric C100H460FM ComPacT NS1000H 4P 1000 A 70 kA MicroLogic 6.0 Moulded Case Circuit Breaker

Schneider Electric's C100H460FM is a 4-pole, 1000 A ComPacT NS1000H moulded case circuit breaker with a 70 kA Icu rating at 380/415 V AC and a 690 V AC operational voltage. The fixed, front-connected breaker uses the MicroLogic 6.0 trip unit for overload (L), short-time delayed short-circuit (S), instantaneous (I) and ground-fault (G) protection.

Selection Notes

The MicroLogic 6.0 trip unit on the C100H460FM 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 NS1000 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.
