Product details

ComPacT NSXm 63H, 50 A, 4P — panel fit and breaking capacity

The C11H4TM050L is a Schneider Electric ComPacT NSXm 63H circuit breaker, 4-pole, rated 50 A at 40 °C with a TM-D thermal-magnetic trip unit. The 108 mm wide, 137 mm high, 80 mm deep body mounts on a backplate, not a DIN rail — plan for a dedicated mounting footprint. Everlink lug terminals accept 2.5…95 mm² rigid or stranded aluminium/copper, or 2.5…70 mm² flexible copper — sized for the 50 A feed without needing a reducer.

For motor-starting or distribution duty where repeated faults aren't expected, this is the figure that governs the panel SCCR. Category A utilisation means it has no intentional short-time delay — it trips fast on a hard fault. The 2000 m operating altitude without derating covers most installations; above that, derate up to 5000 m.

The 12-module 9 mm pitch (108 mm wide) occupies a fixed position — no DIN-rail clip, so pre-drill the mounting holes per the drilling template. Neutral is on the left. The green flag signals presence of auxiliary contacts — visible through the front cover without opening the panel. Toggle control, front-connected on both sides.
