Product details

The C12E3TM160B is a Schneider Electric ComPacT NSXm 160E moulded-case circuit breaker, 3-pole, rated 160 A at 40 °C with a TM-D thermal-magnetic trip unit.

Thermal-magnetic trip means it handles overloads (thermal bimetal) and short-circuits (magnetic coil) in one unit — no separate electronic trip module to set or fail. Utilisation category A means it is not intended for motor starting duty — it is a distribution breaker. The 20,000 electrical cycles at 440 V In/2 and 10,000 at full In give a realistic endurance figure for panel feeder switching, not daily load-break. Mechanical durability is also 20,000 cycles.

Mounts on a backplate (not a DIN rail — this is a bolted-frame MCCB) in horizontal or vertical orientation. Connection is front-facing via compression lugs or busbars; the 35 mm pitch with spreaders (27 mm without) matches standard panel busbar spacing.
