Product details

The Schneider Electric C12H4TM160B is a ComPacT NSXm 4-pole thermal-magnetic moulded-case circuit breaker rated 160 A at 40 °C, with a breaking capacity of 70 kA at 415 V AC (performance level H).

The TM-D trip unit is thermal-magnetic: the thermal element protects against overloads (inverse-time curve), the magnetic element against short-circuits (fixed instantaneous pickup). No earth-leakage protection built in — add a Vigi module externally if needed. Mount it on a backplate (flat on the back, horizontal or vertical) with front-facing connections for compression lugs or busbars.

Mounting and integration notes

Mounts on a backplate, flat on the back, in horizontal or vertical orientation. Front-connect terminals accept compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. The breaker occupies 12 module pitches of 9 mm (108 mm width). Neutral is on the left.

Frequently asked questions

Where can I buy C12H4TM160B and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest pin-compatible alternative to C12H4TM160B in this component family?

Within the ComPacT NSXm family, the closest alternative would be a different trip-unit rating or breaking capacity variant — but the C12H4TM160B is active, so no direct replacement is needed. For a different rating, consult the NSXm selection table.

What compliance documentation does this brand provide for C12H4TM160B (RoHS, REACH, UL, IEC)?

The breaker is certified to EN/IEC 60947-2 and is suitable for isolation per that standard. RoHS and REACH declarations are typically available from Schneider Electric's documentation portal for the ComPacT NSXm series.
