Its 70 kA Icu at 415 V AC (EN/IEC 60947-2) gives solid selectivity headroom for a distribution board feeding motor control centers or lighting panels — the 25 A frame sits comfortably as a feeder or large branch breaker in a 400 V industrial panel. The thermal-magnetic trip provides L (overload) and I (short-circuit) protection with no add-on electronics, so commissioning is straightforward: just torque the terminals and verify the trip curve against the downstream load.
At 415 V AC the C10H3TM025 delivers 70 kA Icu — the H breaking capacity code. That is enough to ride through a fault on a large transformer secondary without the upstream device clearing. At 480 V AC the UL 60947-4-1 rating is 65 kA Icu, so the same breaker works in 480 V distribution as well. For higher-voltage taps the curve drops to 35 kA at 525 V and 10 kA at 690 V AC, which still covers most industrial step-down applications. The 50,000-cycle mechanical endurance and 30,000-cycle electrical endurance at rated current (440 V In) mean this breaker is built for regular switching duty, not just fault backup.
The 161 mm height, 105 mm width, and 86 mm depth fit a standard MCC bucket or panel cutout. IP40 front face keeps dust out; the toggle actuator is IK07 rated against impact.
