Product details

The C10F3TM040C is a Schneider Electric ComPacT NSX100F molded-case circuit breaker, 3-pole, rated 40 A at 50 °C with a thermal-magnetic TM-D trip unit providing overload (L) and short-circuit (I) protection. Its breaking capacity is 36 kA Icu at 380/415 V AC, 50/60 Hz per EN/IEC 60947-2, and it is suitable for isolation per that same standard.

Mounts to a backplate in any orientation — horizontal, vertical, or flat. IP40 enclosure protection and IK07 impact resistance suit it for panel installation where tools are required for access.

Durability and thermal management

Mechanical endurance is 50,000 cycles; electrical endurance reaches 50,000 cycles at 440 V at half rated current (In/2). Power dissipation is 5.47 W per pole — relevant for enclosure thermal calculations when grouping multiple breakers.
