The Schneider Electric A9V19263 is an Acti9 Vigi iC60 add-on residual current device (RCD) — a voltage-independent, 2-pole unit rated 63 A with a 1000 mA AC-type earth-leakage sensitivity, selective time delay, and 230…415 VAC operational range.
The A9V19263 is listed as Obsolete by Schneider Electric. If you are maintaining a panel design that specifies this part, verify whether the wider Acti9 Vigi iC60 range has a current-production variant with the same 2P, 63 A, 1000 mA, AC-type, selective parameters — the physical footprint and connection scheme are consistent across the family, but the order code change and any certification recertification need checking against your assembly documentation.
Wiring and panel integration
Mounts by clip-on onto a DIN rail, occupying 4 x 9 mm pitches (72 mm width). The bottom side is also compatible with comb busbars and distribution blocks, so it can be fed from a common busbar run alongside the MCB. IP20 on the device body, IP40 inside a modular enclosure. Pollution degree 3 per IEC 60947-2 — suitable for standard industrial panel environments, not sealed outdoor locations.
Rated insulation voltage 500 V AC; impulse withstand 6 kV per IEC 60947-2. Impulse withstand on the residual current path: 8/20 µs, 3000 A per IEC 61009-1. Ambient operation -5…60 °C, storage -40…85 °C.
