Product details

What the ratings mean for fit

The C12H6TM160B is a 160 A, 4-pole ComPacT NSXm moulded-case circuit breaker with a thermal-magnetic TM-D trip unit. The 160 A rating at 40 °C is the continuous current the breaker carries without tripping — size the upstream conductor and busbar for that ampacity. The H performance level means it interrupts 70 kA at 415 V AC, which covers most industrial distribution panels fed by a transformer of that voltage class. The 4P configuration switches all four poles (–L3 + N), with the neutral on the left; the neutral is switched but not protected by the TM-D trip. Category A utilisation (per IEC 60947-2) means it is not intended for motor starting or frequent switching — it is a distribution breaker, not a motor-circuit protector.

Frequently asked questions

What is the breaking capacity of C12H6TM160B?

The H performance level gives 70 kA interrupting capacity at 415 V AC, per IEC 60947-2. That is the maximum fault current the breaker can safely clear at that voltage.

What trip unit does C12H6TM160B use?

It uses a fixed thermal-magnetic TM-D trip unit rated 160 A at 40 °C. The thermal element protects against overload; the magnetic element handles short-circuit. It is not field-interchangeable.

What compliance documentation does Schneider provide for C12H6TM160B?

The breaker is certified to EN/IEC 60947-2. It carries IP40 and IK07 protection ratings. For RoHS, REACH, and UL documentation, Schneider provides declarations on request through their product support portal.

Where can I buy C12H6TM160B and how is it quoted?

The C12H6TM160B 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.
