Product details

Three-pole construction (3P) suits three-phase distribution, and the Category A utilisation rating (per EN/IEC 60947-2) confirms it is designed for distribution duty, not motor-starting coordination.

Mounts on a backplate in horizontal or vertical orientation. The 9-module pitch (81 mm wide, 137 mm tall, 80 mm deep) is a standard MCCB footprint — plan the gland plate and DIN-rail fill accordingly. IP40 enclosure protection keeps dust out of a panel interior; no washdown rating, so keep it inside the cabinet. Connection terminals accept compression lugs or busbars, with front-facing connections on both line and load sides.

Certified to EN/IEC 60947-2, with suitability for isolation marked. Pollution degree 3 (IEC 60664-1) means it tolerates conductive pollution in industrial panels. Overvoltage category III suits fixed-installation distribution. Mechanical durability is 20,000 cycles; electrical durability is 20,000 cycles at 440 V at rated current, halving to 10,000 cycles at 2× rated current — the duty cycle matters if the breaker sees frequent switching.

Frequently asked questions

Where can I buy C11N3TM080B?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of C11N3TM080B?

The breaking capacity is 50 kA at 415 V AC (performance level N), which is the standard high-fault rating for the ComPacT NSXm frame.

What standards does C11N3TM080B comply with?

It is certified to EN/IEC 60947-2 and is suitable for isolation per that standard. Pollution degree 3 and overvoltage category III apply.
