Schneider Electric C10N3TM025 ComPacT NSX100N 3P 25 A 50 kA TM-D Fixed Moulded Case Circuit Breaker

Schneider Electric's C10N3TM025 is a 3-pole ComPacT NSX100N moulded case circuit breaker rated 25 A, delivering 50 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 300 A instantaneous short-circuit trip, fixed-mounted for low-voltage distribution boards.

Selection Notes

The N-coded frame carries a baseline breaking capacity of 50 kA Icu at 380/415 V AC within the ComPacT NSX100 range — suited to standard LV distribution boards without unusually high prospective fault current. 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 300 A — so no separate instantaneous relay is needed. Within the same NSX100N frame, pick the 25 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.
