The A9C62225 is a Reflex iC60N Ti24 integrated control circuit breaker from the Acti9 range, combining overcurrent protection with local and remote switching in a single DIN-rail module. It's a 25 A, 2-pole device with a C curve, rated for 230 V AC supply voltage and offering a 20 kA breaking capacity at 230...240 V AC per EN/IEC 60947-2. The thermal-magnetic trip unit handles both overload and short-circuit faults, while the integrated control allows ON/OFF toggle, remote pulse, or continuous command via the control circuit voltage options (230 V AC, 24 V AC, 48 V AC, 24 V DC, 48 V DC). This is a panel-building part for distribution and control circuits where you need to save space and wiring by combining a contactor and an MCB in one unit.
At 380...415 V AC, the breaking capacity drops to 10 kA Icu, so if you're on a 400 V system, that's your number. The 2 poles protect both phase and neutral in a single-phase circuit, or two phases in a three-phase system. The 500 V AC rated insulation voltage (Ui) tells you the insulation system is rated for that voltage class, which is fine for standard 230/400 V networks.
The fixed mounting mode means it's not a plug-in base; you wire it directly. At 81 mm wide (9 x 9 mm pitches), it takes up 9 module spaces on the rail, so plan your enclosure fill accordingly. Depth is 77 mm, height 84 mm. The padlockable handle (OFF position only) adds lockout/tagout capability for maintenance safety. The green LED for ON, red for fault, and flashing patterns for overheat/trip/ready give you status at a glance without needing a separate indicator.
Durability and environmental ratings
Electrical durability is rated at 50,000 cycles under AC-1 (resistive load) at 50 Hz — that's the expected life before the contacts wear out under normal switching. Mechanical durability matches at 50,000 cycles. Tropicalisation class 2 indicates it's treated for operation in high-humidity conditions (93% RH at 40 °C). Earth-leakage protection requires a separate block — this breaker doesn't include integral RCD protection.
