The C25F4TM200 is a 200 A, 4-pole ComPacT NSX250F moulded-case circuit breaker with a thermal-magnetic TM-D trip unit, built to EN/IEC 60947-2 for distribution duty. At 415 V AC the rating drops to 36 kA Icu, still enough for most European distribution boards. The TM-D trip gives you thermal overload (L) and magnetic short-circuit (I) protection in one block; no earth-leakage module is fitted, so if you need residual-current detection you add a Vigi or external RCD downstream.
Front connections top and bottom, 35 mm connection pitch. The 4-pole body is 140 mm wide, 161 mm high, 86 mm deep.
Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V at half rated current (10,000 at full current). Suitability for isolation is confirmed per EN/IEC 60947-2 — the toggle mechanism provides a visible break. Category A utilisation means it is not intended for frequent motor switching under load; its job is distribution protection.
