The Schneider Electric C60H3P4AC is a 3-pole miniature circuit breaker from the Multi9 C60 range, rated 4 A at 30 °C with a C curve (magnetic trip 5...10 x In). The 73 mm depth leaves room behind the gland plate for wiring — tunnel terminals accept up to 25 mm² rigid or 16 mm² flexible, with a 14 mm strip length and 2 N·m tightening torque.
The C60H3P4AC carries 30 kA Icu at 230...240 V AC, 15 kA at 400...415 V AC, and 10 kA at 440 V AC — all per IEC 60947-2. That means it handles typical industrial fault levels on a 400 V three-phase distribution board.
The toggle actuator gives clear ON/OFF indication and a contact position indicator confirms the state of the moving contacts. Earth-leakage protection requires a separate block — not built in. Ambient operating range -25 to 60 °C, storage -40 to 70 °C, with tropicalisation class 2 (conforming to IEC 60068-1) for humid environments up to 95 % RH at 55 °C.
