Schneider Electric C10V3TM040 ComPacT NSX100HB1 3P 40 A 75 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C10V3TM040 is a ComPacT NSX100HB1 molded case circuit breaker built for distribution circuits. Configured as 3P, it is rated for 40 A continuous current with a 75 kA breaking capacity (Icu) at 690 V AC, and carries a TM-D thermal-magnetic trip unit for overload and short-circuit protection (LI).

Selection Notes

The C10V3TM040 sits on the NSX100HB1 frame (a 690 V-rated frame for medium-voltage-adjacent AC distribution) 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 40 A nameplate rating without changing the device. The 75 kA Icu at 690 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.
