Product details

160 A MCCB for distribution boards — what the ratings mean

The C12N6TM160B is a Schneider Electric ComPacT NSXm 4-pole moulded-case circuit breaker rated 160 A at 40 °C with a 50 kA breaking capacity at 415 V AC (N performance level). The thermal-magnetic TM-D trip unit gives you a fixed thermal curve for overload protection plus a magnetic instantaneous pickup for short circuits; no interchangeable trip blocks, so the 160 A rating is what you spec into the BOM. Mounts on a backplate, front-connected top and bottom, compression lug or busbar terminations. The 4-pole version (3 phases + switched neutral) suits TN or TT systems where you need neutral isolation.

Backplate-mounted, 108 mm wide × 137 mm high × 80 mm deep — occupies 12 module pitches at 9 mm each. Horizontal or vertical mounting, flat on the back.

Suitability for isolation is confirmed — the breaker provides visible isolation when open. The grey RAL 7016 colour is the standard NSXm finish.

Frequently asked questions

Where can I buy C12N6TM160B and how do I get a price?

The C12N6TM160B is sourced and quoted 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 breaking capacity of C12N6TM160B?

The C12N6TM160B has a 50 kA breaking capacity at 415 V AC (N performance level) per IEC 60947-2. This is the maximum short-circuit current it can safely interrupt at that voltage.

What trip unit does C12N6TM160B use?

It uses a fixed thermal-magnetic TM-D trip unit rated 160 A at 40 °C. The thermal element provides overload protection; the magnetic element provides instantaneous short-circuit pickup. The trip rating is not field-interchangeable.

What compliance documentation is available for C12N6TM160B?

The C12N6TM160B is designed and tested to EN/IEC 60947-2. It carries suitability for isolation per that standard. Standard compliance documentation (declaration of conformity, test reports) is available through the manufacturer's documentation portal.
