Product details

The C11N4TM050L is a Schneider Electric ComPacT NSXm 4-pole circuit breaker with a TM-D thermal-magnetic trip unit rated 50 A at 40 °C. It's built to EN/IEC 60947-2 for distribution duty, with a 50 kA breaking capacity at 415 V AC — that's the N-level performance, meaning it can clear a fault up to 50 kA without welding or rupturing, which is the spec that decides whether this breaker coordinates with downstream gear in a panel.

Front-connected terminals use Everlink lugs — one lug per pole, accepting 2.5 to 95 mm² rigid or stranded aluminium/copper, or 2.5 to 70 mm² flexible copper.

Environment and protection

Rated IP40 (finger-safe, no water ingress) and IK07 impact resistance. The grey RAL 7016 finish is standard for the ComPacT line.

Frequently asked questions

What is C11N4TM050L's breaking capacity?

50 kA at 415 V AC, N-level performance per the ComPacT NSXm range. That's the short-circuit rating that governs selectivity and SCCR coordination in a distribution panel.
