Product details

The C11N3TM063B is a Schneider Electric ComPacT NSXm 3-pole thermal-magnetic circuit breaker rated 63 A at 40 °C, with a 50 kA breaking capacity at 415 V AC — the N performance level per IEC 60947-2. Mounts on a backplate via the 9-module 81 mm wide footprint. Front terminals accept compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. IP40 front face, IK07 impact rating — suitable for enclosed panel installation where accidental tool drops or debris are a concern.

Standards & approvals

Designed to EN/IEC 60947-2, suitability for isolation marked (yes). IK07 mechanical impact, IP40 ingress protection. Electrical durability: 20,000 cycles at 440 V In/2, 10,000 at 440 V In, 10,000 at 690 V In/2, 5,000 at 690 V In. Mechanical durability: 20,000 cycles. Relative humidity 0–95%.

Frequently asked questions

What is the breaking capacity of C11N3TM063B?

The N performance level gives 50 kA at 415 V AC, per IEC 60947-2. That is the maximum prospective fault current the breaker can safely interrupt at that voltage.

Where can I buy C11N3TM063B and how is it quoted?

C11N3TM063B is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here.
