Product details

The Schneider Electric C11B6TM025B is a ComPacT NSXm 63B frame moulded-case circuit breaker (MCCB) with four poles (4P), a thermal-magnetic TM-D trip unit, and a 25 A rating at 40 °C. It's designed for distribution duty in commercial and industrial panels, built to EN/IEC 60947-2.

Integration and mounting — panel fit

The 108 mm width spans 12 module pitches at 9 mm each, so it occupies a predictable footprint in a multi-breaker lineup. Connection terminals accept compression lugs or busbars, front-connected both top and bottom — no rear-access required. Neutral is on the left. IP40 enclosure protection and IK07 impact resistance suit it for enclosed panel mounting where occasional tool contact or debris is a concern.

Frequently asked questions

How do I get current pricing and availability for C11B6TM025B?

The C11B6TM025B is sourced to order against an RFQ through independent distribution. Submit a request for quote; pricing and stock status are confirmed at that time.

What is C11B6TM025B's breaking capacity?

Performance level B: 25 kA at 415 V AC. That's the maximum fault current it can safely interrupt at that voltage without upstream protection needing to clear.

What standards does C11B6TM025B comply with?

It is designed and certified to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear — specifically for circuit breakers. It also carries suitability for isolation per that standard.
