The C10F32D040 is a Schneider Electric ComPacT NSX100F circuit breaker in the ComPacT range, fitted with a MicroLogic 2.2 electronic trip unit rated 40 A at 40 °C. It is a 3-pole unit built on the NSX100F frame, which means the breaker body and bus-bar connections are sized for 100 A maximum — the 40 A trip rating is set by the plug-in MicroLogic module, not the frame. That gives you headroom to re-trip to a higher rating later by swapping the trip unit, without pulling the breaker off the backplate. The electronic trip unit provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) protection curves. At 240 V AC it delivers 85 kA Icu; at 415 V AC it is 36 kA Icu; at 690 V AC it drops to 8 kA Icu.
Mounts on a backplate in any orientation — horizontal, vertical, or flat on the back. The 105 mm width, 161 mm height, and 86 mm depth fit standard ComPacT NSX cutouts; the 35 mm connection pitch aligns with common bus-bar systems. Front connections on both line and load sides simplify bus-bar routing and cable entry in a gland-plate layout. IP40 enclosure protection means it is suitable for clean indoor panels; IK07 impact resistance handles incidental tool contact during commissioning.
