Product details

Panel integration note

The C25B32D100 is a 3-pole ComPacT NSX moulded-case circuit breaker rated 100 A at 40 °C with a MicroLogic 2.2 electronic trip unit. It mounts flat on a backplate — no DIN-rail clip — so plan for a dedicated panel footprint. IP40 enclosure protection and IK07 impact resistance mean it is suited for dry indoor panels where accidental tool contact is possible.

Breaking capacity and trip unit

Rated 40 kA Icu at 220/240 V AC, 25 kA Icu at 380/415 V AC, and 20 kA Icu at 440 V AC per IEC 60947-2. The MicroLogic 2.2 electronic trip unit provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection. This matters for motor or transformer feeders where repeated starts can accumulate heat.

Compliance documentation covers EN/IEC 60947-2 for the breaker standard. The IP40 and IK07 ratings are factory-tested per IEC 60529 and IEC 62262. No earth-leakage module is integrated — specify a separate Vigi add-on if ground-fault protection is required.

Frequently asked questions

What is the breaking capacity of C25B32D100 at 415 V?

25 kA Icu at 380/415 V AC per IEC 60947-2, which is the B breaking capacity code for this unit.

Where can I buy C25B32D100 and how is it quoted?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures are published here.

What trip unit does C25B32D100 use?

It uses a MicroLogic 2.2 electronic trip unit providing L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection.

What are the mounting dimensions of C25B32D100?

Width 105 mm, height 161 mm, depth 86 mm. It mounts flat on a backplate — not DIN-rail — with front connection on both line and load sides.
