The Schneider Electric C10F6TM025C is a ComPacT NSX100F moulded-case circuit breaker (MCCB) with a 25 A thermal-magnetic TM-D trip unit, four poles, and a 36 kA interrupting rating at 415 V AC.
The TM-D unit provides thermal overload protection (L) and magnetic short-circuit protection (I), a standard combination for feeder and branch-circuit protection in distribution panels. Breaking capacity is the key selection parameter for fault duty. At 415 V AC — common in European industrial networks — the C10F6TM025C delivers 36 kA Icu. At 220/240 V the rating rises to 85 kA; at 690 V it drops to 8 kA. Selectivity studies should use the voltage closest to the actual system. Rated for 50,000 mechanical cycles and 30,000 electrical cycles at rated current (440 V In), this breaker is built for panel duty where occasional switching is expected, not continuous motor-starting service.
The 140 mm width for a 4-pole frame is standard for the NSX100 footprint. IP40 enclosure protection and IK07 impact resistance suit it for enclosed panel installation where occasional tool contact or debris is a concern. The toggle control provides local manual operation.
