Schneider Electric C10H3TM025 ComPacT NSX100H 3P 25 A 70 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C10H3TM025 is a ComPacT NSX100H molded case circuit breaker built for distribution circuits. Configured as 3P, it is rated for 25 A continuous current with a 70 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 C10H3TM025 sits on the NSX100H frame (a high breaking-capacity frame) 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 25 A nameplate rating without changing the device. The 70 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. 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.
