Schneider Electric C10F1TM100 ComPacT NSX100F 1P 100 A 18 kA at 240 V TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C10F1TM100 is a 1P ComPacT NSX100F moulded case circuit breaker rated 100 A, dual-rated for AC (277 V) and DC (250 V) circuits, with an 18 kA breaking capacity (Icu) at 240 V AC. It uses a fixed, non-adjustable TM-D thermal-magnetic trip unit, giving compact, low-maintenance overload and short-circuit protection in small-frame distribution and DC applications.

Selection Notes

The TM-D trip unit on this NSX100F frame is fixed rather than adjustable: L overload protection is set at 1 x In and I instantaneous protection trips at 800 A, so the 100 A rating itself is the only selection variable — pick it to sit just above the circuit's full-load current. Use the 1-pole version on a single AC line-to-neutral or two-wire DC circuit; it is not a substitute for a 2-pole device on a two-wire ungrounded or floating AC circuit. Because the breaker is dual-rated for AC and DC, the same part also fits DC distribution and battery circuits up to 250 V DC, where the 18 kA AC Icu figure does not apply and the 36 kA DC rating governs instead.
