Product details

The 25 A figure is the trip-unit rating at 40 °C ambient; if your panel runs hotter, you derate per the IEC 60947-2 thermal curve. The TM-D gives you fixed thermal overload (L) and fixed magnetic short-circuit (I) protection — no adjustable dials, so what you see on the nameplate is what you get for coordination studies. At 480 V AC it delivers 50 kA Icu under UL 60947-4-1.

This breaker mounts to a backplate — no DIN rail required. The enclosure itself provides the environmental seal. IK07 impact resistance handles accidental tool drops during panel work.

Frequently asked questions

What compliance documentation comes with the C10N4TM025?

The breaker is certified to EN/IEC 60947-2 and UL 60947-4-1. It carries suitability for isolation per EN/IEC 60947-2, pollution degree 3 per IEC 60664-1, and overvoltage category III. Schneider provides the declaration of conformity and test certificates with the shipment.
