The Schneider Electric A9V14463 is an Acti9 Vigi iC60 add-on residual current device (RCD) — 4 poles, rated 63 A, with a 300 mA AC-type earth-leakage sensitivity, instantaneous trip, for 230…415 V AC networks at 50/60 Hz.
The tunnel-type terminals on the bottom accept 1…35 mm² rigid or 1…25 mm² flexible cable, with a stripping length of 14 mm and a tightening torque of 3.5 N·m. The 4-pole unit occupies 7 modules of 9 mm pitch (135 mm width). IP20 on the body, IP40 inside a modular enclosure — suitable for dry indoor panel environments only.
The residual current tripping technology is voltage-independent, meaning it will still trip on a ground fault even if the line voltage is lost — a reliability advantage for safety circuits. The 8/20 µs impulse withstand rating of 250 A per IEC 61009-1 indicates it can survive surge events without nuisance tripping.
