The Schneider Electric A9C52425 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 25 A, 4-pole, curve C thermal-magnetic MCB with a remote-control toggle function. It combines overcurrent protection with a motorised switching element, so the same DIN-rail device handles both manual isolation and remote ON/OFF commands via a maintained or impulse control signal.
The 4-pole version (4P) switches all phases and neutral, common for three-phase distribution in panel builds. Breaking capacity is 20 kA Icu at 220…240 V AC and 10 kA Icu at 380…415 V AC, both per EN/IEC 60947-2. That 20 kA figure at the common 230/240 V level means it can interrupt high fault currents on a strong utility feed without upstream fuses — useful for main incomer or sub-distribution positions where SCCR needs to stay high. Control circuit voltage options cover 230 V AC, 24 V AC, 48 V AC, 24 V DC, and 48 V DC — so the same breaker body works with a building-management 24 VDC PLC output or a conventional 230 VAC pushbutton circuit. The control signal type accepts both maintained (steady ON/OFF) and impulse (momentary-pulse) commands, matching most remote-control schemes. IP20 finger-safe terminals are standard for enclosed panel use.
Occupies 13 x 9 mm pitches (117 mm wide) on the DIN rail — that's a 4-module width in the Acti9 footprint. Depth is 77 mm, height 84 mm. The fixed mounting mode means it clips directly onto the rail; no additional base or adapter needed. Local signalling includes a green LED for device ON, red LED for fault, flashing LED for trip/overheat, and a separate flashing LED for device-ready status — so a technician can read the breaker's state from across the cabinet without a meter.
