Product details

The Schneider Electric C10B4TM025 is a ComPacT NSX100B circuit breaker with a 25 A thermal-magnetic TM-D trip unit, 4 poles, and a breaking capacity of 40 kA Icu at 220/240 V AC 50/60 Hz per EN/IEC 60947-2. It is rated Category A (no intentional short-time delay) and suitable for isolation per EN/IEC 60947-2 — meaning you can use it as a disconnecting means for the downstream circuit.

Mounts on a backplate (not DIN rail), in horizontal or vertical orientation, flat on the back. Front connections on both line and load sides — no rear-access required, which simplifies panel layout. The 35 mm connection pitch matches standard busbar systems. IP40 enclosure protection keeps dust out; IK07 impact resistance handles incidental tool drops during commissioning.
