Schneider Electric C10W3TM063 ComPacT NSX100HB2 3P 63 A 100 kA TM-D Fixed Moulded Case Circuit Breaker

Schneider Electric's C10W3TM063 is a 3-pole ComPacT NSX100HB2 moulded case circuit breaker rated 63 A, delivering 100 kA breaking capacity (Icu) at 690 V AC and a 690 V AC operational voltage (Ue). Its TM-D thermal-magnetic trip unit pairs adjustable overload protection with a fixed 500 A instantaneous short-circuit trip, fixed-mounted for low-voltage distribution boards.

Selection Notes

The HB2 code marks this as a 690 V AC frame rated 100 kA Icu at that voltage, the highest 690 V breaking-capacity tier in this range. 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 500 A — so no separate instantaneous relay is needed. Within the same NSX100HB2 frame, pick the 63 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.
