Schneider Electric C11N6TM032B ComPacT NSXm 63N 4P 32 A 50 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C11N6TM032B is a 4P ComPacT NSXm 63N moulded case circuit breaker rated 32 A at 40°C, built on a TM-D thermal-magnetic trip unit with 50 kA breaking capacity (Icu) at 380/415 V AC. This 4P version has protected poles 3D (neutral not protected). It is a fixed-mounting device with front compression lug or busbar connection for low-voltage distribution circuits up to 690 V AC.

Selection Notes

Choose the N performance level (50 kA Icu at 380/415 V AC) when the prospective short-circuit current at the installation point stays at or below that rating; move to the lower-breaking-capacity F or B version in the same NSXm frame if the fault-level study gives a different result. The neutral pole is not protected (3D), which fits TN-S boards where neutral overcurrent protection is handled elsewhere. The TM-D trip unit has a fixed long-time delay with pickup adjustable over 0.7...1 x In range and a fixed instantaneous pickup at 600 A, so downstream coordination relies on current discrimination rather than time grading.
