Product details

It carries an 85 kA Icu breaking capacity at 500 V AC 50/60 Hz per EN/IEC 60947-2, making it a distribution-grade breaker for high-fault panels where the available short-circuit current exceeds what a standard 25/36 kA unit can handle. Pollution degree 3 (IEC 60664-1) means it tolerates conductive dust and condensation typical in industrial enclosures — no derating needed for the panel environment itself, just watch the altitude above 2000 m.

The 4-pole version with neutral left (1 x Ir protection on the 4D setting) handles three-phase plus neutral distribution where the neutral is fully rated — not just a switched pole.

IP40 front face and IK07 impact rating keep it safe in a locked panel where only qualified personnel open the door. No earth-leakage module built in — if ground-fault protection is required, add a Vigi module externally.

Frequently asked questions

Where can I buy C25V4TM250 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is C25V4TM250's breaking capacity at 690 V?

The breaking capacity code is HB1, which means 75 kA Icu at 660/690 V AC 50/60 Hz per IEC 60947-2. At 500 V AC it is 85 kA, and at 525 V it is 80 kA.

What compliance documentation does this brand provide for C25V4TM250?

The breaker is certified to EN/IEC 60947-2 and carries suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1. IP40 and IK07 per IEC 60529 and IEC 62262 respectively.
