Product details

The C125N4WM is a basic frame from the Schneider Electric ComPacT NS630b...1600 new generation range — a manually operated, withdrawable 4-pole unit rated 1250 A at 50 °C.

Mounts withdrawable on a backplate with a 70 mm connection pitch. The 306 mm width and 260 mm height mean it fills a standard panel cubicle opening; depth is 147 mm. Neutral sits on the left.

Frequently asked questions

What is the C125N4WM rated breaking capacity at 415 V AC?

50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. The Ics (service breaking capacity) at the same voltage is also 50 kA, meaning it can reclose and carry rated current after a fault at that level without derating.

Where can I buy the C125N4WM?
