Schneider Electric C10R3TM100 ComPacT NSX100R 3P 100 A 200 kA TM-D Fixed Moulded Case Circuit Breaker

Schneider Electric's C10R3TM100 is a 3-pole ComPacT NSX100R moulded case circuit breaker rated 100 A, delivering 200 kA breaking capacity (Icu) at 415 V AC and a 690 V AC operational voltage (Ue). Its TM-D thermal-magnetic trip unit pairs adjustable overload protection with a fixed 800 A instantaneous short-circuit trip, fixed-mounted for low-voltage distribution boards.

Selection Notes

The R-coded frame carries a very-high breaking capacity of 200 kA Icu at 380/415 V AC, well above the standard tiers in the ComPacT NSX100 range — suited to incomers or distribution points where prospective fault current is high, such as close to a transformer. Its TM-D thermal-magnetic trip unit combines the LI protection set in one block: L is the overload (thermal) function, adjustable 0.7–1 × In, and I is the short-circuit (magnetic) function, fixed at 800 A — so no separate instantaneous relay is needed. Within the same NSX100R frame, pick the 100 A trip rating to match the protected circuit's full-load current — lower- and higher-current variants share the same breaking capacity and enclosure footprint.
