Schneider Electric C10W4TM063 ComPacT NSX100HB2 4P 63 A 100 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C10W4TM063 is a ComPacT NSX100HB2 molded case circuit breaker built for distribution circuits. Configured as 4P, it is rated for 63 A continuous current with a 100 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 C10W4TM063 sits on the NSX100HB2 frame (the highest-Icu 690 V-rated frame in the ComPacT NSX100 line) 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 63 A nameplate rating without changing the device. The 100 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. 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.
