Product details

The Schneider Electric C11B3TM032B is a ComPacT NSXm 3-pole circuit breaker with a TM-D thermal-magnetic trip unit rated 32 A at 40 °C. It is designed for distribution applications per EN/IEC 60947-2, with a breaking capacity of 25 kA at 415 V AC (performance level B). The 32 A rating at 40 °C means the breaker carries its full rated current in a 40 °C ambient — no derating needed at typical panel temperatures.

The 9-module pitch (9 x 9 mm = 81 mm width) fits standard DIN-rail enclosures. Connection is front-facing via compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. IP40 front protection means it is sealed against tools and small objects — suitable for enclosed panel installation, not washdown areas.

Frequently asked questions

What is the breaking capacity of C11B3TM032B?

The C11B3TM032B has a breaking capacity of 25 kA at 415 V AC (performance level B per EN/IEC 60947-2). This is the maximum fault current it can safely interrupt at that voltage.

What trip unit does C11B3TM032B use?

It uses a TM-D thermal-magnetic trip unit rated 32 A at 40 °C. The thermal element protects against overload; the magnetic element provides short-circuit protection.

Where can I buy C11B3TM032B?

The C11B3TM032B is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing.
