Product details

It provides distribution-level overcurrent protection and isolation, certified to EN/IEC 60947-2.

Mounts on a backplate in horizontal or vertical orientation. The 108 mm width occupies 12 module pitches at 9 mm each — standard for DIN-rail panel layouts. Front-facing connections accept compression lugs or busbars; neutral is on the left.

Environmental and electrical ratings

IP40 enclosure protection (IK07 impact) suits clean indoor panels. Electrical durability: 20,000 cycles at 440 V at rated current, 10,000 cycles at 440 V at In, and 5,000 cycles at 690 V at In.

Frequently asked questions

What is the breaking capacity of C11B4TM025B?

25 kA at 415 V AC (performance level B), which is the maximum fault current it can safely interrupt at that voltage.

What standards does C11B4TM025B comply with?

It complies with EN/IEC 60947-2 for circuit breakers and IEC 60664-1 for pollution degree 3.

Where can I buy C11B4TM025B?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
