Product details

The Schneider Electric C11E4TM063B is a ComPacT NSXm 4-pole moulded-case circuit breaker rated 63 A at 40 °C with a 16 kA breaking capacity at 415 V AC (performance level E). The 4-pole design with neutral left suits distribution boards where you need full isolation on all poles.

Above that, the thermal element starts to track the heat curve — so if your enclosure runs hot, you derate. The mechanical durability of 20 000 cycles and electrical durability of 10 000 cycles at 440 V In tell you it's built for routine switching, not just backup protection.

The 108 mm width fits a 12-module pitch at 9 mm per module. Connection pitch is 35 mm with spreaders, 27 mm without.
