Schneider Electric C10R4TM100 ComPacT NSX100R 4P 100 A 200 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C10R4TM100 is a ComPacT NSX100R molded case circuit breaker built for distribution circuits. Configured as 4P, it is rated for 100 A continuous current with a 200 kA breaking capacity (Icu) at 415 V AC, and carries a TM-D thermal-magnetic trip unit for overload and short-circuit protection (LI).

Selection Notes

The C10R4TM100 sits on the NSX100R frame (the highest breaking-capacity frame in the ComPacT NSX100 line, built for applications close to the supply transformer) with an adjustable TM-D trip unit: the long-time pick-up Ir can be set from 0.7 to 1 x In, so the same physical breaker covers a current range below its 100 A nameplate rating without changing the device. The 200 kA Icu at 415 V AC sets how far downstream from the source this breaker can sit before a lower-breaking-capacity frame becomes unsafe to use. The neutral pole carries its own protection (4D, 1 x Ir), which matters on 4-wire systems with significant harmonic or unbalanced neutral current. It also carries a Yes rating for isolation duty under EN/IEC 60947-2, so a correctly installed unit can serve as the circuit's local disconnecting means.
