Product details

Panel-builder commissioning notes

The 100 kA Icu at 240 V AC (70 kA at 415 V AC, 65 kA at 440 V AC) means it handles high fault currents typical in distribution panels without cascading upstream — you can place it closer to the transformer without a current-limiting fuse ahead of it. The TM-D trip gives you thermal overload (L) and magnetic short-circuit (I) protection, no ground-fault module. At 40 A and 40 °C ambient, it's sized for a 40 A feeder or a motor branch circuit with proper coordination study. Front connections top and bottom, neutral on the left. IK07 impact rating handles accidental tool drops during commissioning. Electrical durability is 50,000 cycles at 440 V at half rated current, 30,000 at full rated current — enough for frequent switching in a distribution role but not for a motor-starting duty where you'd want a contactor ahead of it. Mechanical durability matches at 50,000 cycles.

Frequently asked questions

What is C10H4TM040's breaking capacity at 415 V?

70 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2. The frame code is H, which stands for 70 kA at 415 V AC.

What is the closest alternative to C10H4TM040 in the same family?

Within the ComPacT NSX 100H frame, the closest sibling would be a unit with the same 4-pole 40 A rating but a different trip unit — for example, an electronic Micrologic trip instead of the TM-D thermal-magnetic. The physical footprint, breaking capacity, and mounting are identical; the trip curve and adjustability differ. Pin compatibility is the same for the frame and accessories.
