The Schneider Electric C60H1P3AD is a 1-pole miniature circuit breaker from the Multi9 C60 range, rated 3 A with a D tripping curve.
Rated breaking capacity (Icu) hits 15 kA at 230...240 V AC per IEC 60947-2, and 20 kA at 60 V DC on a single pole. At 400...415 V AC it drops to 4 kA — still enough for most final subcircuits in a 400 V distribution board, but you'll want to check the upstream device's let-through if your fault current at that voltage exceeds 4 kA.
Occupies 2 modules of 9 mm pitch (18 mm wide) on the DIN rail. Depth is 73 mm, height 81 mm. The toggle gives local ON/OFF indication, and the contact position indicator shows the true state of the contacts — useful during panel commissioning when the handle might be locked off.
Environmental and isolation specs
Tropicalisation level 2 per IEC 60068-1 handles humidity up to 95% at 55 °C — fine for coastal or unconditioned plant rooms. Impulse withstand voltage is 6 kV.
