The Schneider Electric A9V14225 is a Vigi iC60 add-on residual current device (RCD) from the Acti9 range, designed to clip onto the side of an iC60 MCB to provide earth leakage protection in a 2-pole configuration. Rated at 25 A with a 300 mA sensitivity, it is a Type AC (sinusoidal AC only) voltage-independent instantaneous trip unit, meaning it operates without needing an external power supply — the fault current itself triggers the mechanism. It mounts on a DIN rail via clip-on and occupies 3 x 9 mm pitches (63 mm wide), fitting standard modular enclosures with an IP40 face and IP20 terminal protection.
The 230...415 V AC operational voltage range (50/60 Hz) covers single-phase and two-phase line-to-line applications across standard European and Asian distribution networks. The 8/20 µs impulse withstand of 250 A (per IEC 61009-1) confirms the RCD can survive surge currents from nearby lightning or switching events without damage.
The A9V14225 is listed as obsolete by Schneider Electric. No direct official successor order code is provided in the available records, so replacement typically requires reviewing the current Acti9 Vigi iC60 catalog for a functionally equivalent 2P 25A 300mA Type AC add-on block.
Wiring and integration notes
The add-on block connects to the iC60 MCB via screws (tunnel-type terminals), accepting 1 to 25 mm² rigid or 1 to 16 mm² flexible conductors on the bottom side. A trip indicator provides local visual signalling of RCD operation, and the unit is compatible with bottom-entry comb busbars and distribution blocks. Depth of 73.5 mm and height of 91 mm fit standard Acti9 enclosures; verify clearance for the add-on block when mounted adjacent to other devices on the same DIN rail.
