The Schneider Electric A9V26425 is an Acti9 Vigi iC60 add-on residual current device (RCD) — 4 poles, rated 25 A, with a 500 mA Type A earth-leakage sensitivity.
The 500 mA sensitivity is an adjustable or fixed high-threshold trip — suited to circuits where nuisance tripping from leakage in long cable runs or equipment filters must be avoided, such as distribution sub-mains or industrial socket outlets. The trip is instantaneous (no intentional time delay), so it clears a fault within the IEC 61009-1 trip-time curve. Voltage-independent tripping technology means the RCD operates regardless of whether the supply voltage is present — it draws its trip energy from the fault current itself. This is critical for safety when the neutral or phase is lost upstream. IP20 on the body, IP40 inside a modular enclosure.
Tightening torque 2 N·m, strip length 14 mm. Bottom busbar compatible for distribution wiring.
