Schneider Electric C11B3TM100B ComPacT NSXm 160B 3P 100 A 25 kA TM-D Fixed Moulded Case Circuit Breaker

Schneider Electric's C11B3TM100B is a 3-pole ComPacT NSXm 160B moulded case circuit breaker rated 100 A, delivering 25 kA breaking capacity (Icu) at 415 V AC and a 440 V AC operational voltage (Ue). Its TM-D thermal-magnetic trip unit pairs adjustable overload protection with a fixed 1250 A instantaneous short-circuit trip, fixed-mounted for low-voltage distribution boards.

Selection Notes

The B performance level delivers 25 kA Icu at 380/415 V AC on the 160 A NSXm frame — the higher-current end of the ComPacT NSXm range, still sized for final distribution rather than incomers. Everlink spring-clamp auxiliary connections and DIN-rail or plate mounting are built in. 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 1250 A — so no separate instantaneous relay is needed. Within the same NSXm 160B 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.
