The Schneider Electric C12E6TM160L is a ComPacT NSXm 160E molded-case circuit breaker rated 160 A at 40 °C, 4-pole, with a thermal-magnetic TM-D trip unit and a 16 kA interrupting capacity at 415 V AC (performance level E). It's a distribution-grade MCCB built to EN/IEC 60947-2, suitable for isolation per that standard.
The TM-D trip unit combines a thermal bimetal for overload protection and a magnetic coil for short-circuit response — no electronic adjustments, which keeps it simple and field-reliable. Category A utilization means it's not intended for selectivity under short-circuit conditions with other breakers in series unless specifically coordinated.
The 108 mm width occupies 12 modules of 9 mm pitch on a DIN rail. Connection pitch is 35 mm with spreaders, 27 mm without. The Everlink lug terminals accept flexible copper from 2.5 to 70 mm² or rigid/stranded copper up to 95 mm² — that's a wide enough range to land most feeder cables without adapters. IK07 impact rating handles incidental tool contact during panel work.
