The C10F4TM025C is a Schneider Electric ComPacT NSX100F molded-case circuit breaker with a 25 A thermal-magnetic TM-D trip unit, 4 poles, and a breaking capacity code of F — 36 kA Icu at 415 V AC. It's designed for distribution applications in commercial and industrial panels, mounted on a backplate with front-facing connections.
The F-frame delivers 85 kA Icu at 220/240 V AC, 36 kA at 380/415 V, 35 kA at 440 V, 25 kA at 500 V, 22 kA at 525 V, and 8 kA at 660/690 V AC — all per IEC 60947-2.
The TM-D trip unit provides thermal-magnetic protection: the L curve handles overloads (thermal, adjustable), and the I curve covers short-circuits (magnetic, fixed). Rated 25 A at 50 °C, it's suited for protecting feeder circuits or downstream sub-distribution boards. Neutral protection is set at 1 x Ir for 4-pole configurations.
Mechanical durability is 50,000 cycles; electrical durability varies with voltage and load — 50,000 cycles at 440 V at half rated current, 30,000 at full rated current, and 10,000 at 690 V full rated. It's certified for isolation per EN/IEC 60947-2, meaning it can be used as a visible-break disconnect in the circuit.
