Product details

The C10B4TM050C is a Schneider Electric ComPacT NSX100B circuit breaker, 4-pole, with a TM-D thermal-magnetic trip unit rated 50 A at 50 °C. The breaking capacity is 40 kA Icu at 220/240 V AC, 25 kA Icu at 380/415 V AC, and 20 kA Icu at 440 V AC — all per IEC 60947-2. The thermal-magnetic trip provides L (overload, thermal) and I (short-circuit, magnetic) protection in one unit.

Deployment context

Mounts on a backplate, accepts front connections top and bottom. The 140 mm width and 161 mm height fit standard distribution panel cutouts. IP40 enclosure protection means it is suited for indoor panel installation where tools are required to access live parts. The toggle control provides manual on/off and trip indication.
