The Schneider Electric A9W24363 is an Acti9 Vigi iC60 add-on residual current device (RCD) rated 63 A with 300 mA Type A earth leakage protection, instantaneous trip, and voltage-independent tripping technology.
63 A rated current (In) matches the downstream iC60 MCB rating — pair them for coordinated overcurrent and earth leakage protection on a 63 A circuit. 300 mA sensitivity is typical for submain or feeder protection where nuisance tripping on leakage from distributed loads must be avoided; Type A detects pulsating DC residual currents common in electronics and single-phase rectifier loads. Voltage-independent tripping means the RCD operates even if the phase voltage collapses — critical for safety when the supply is degraded.
Terminal tunnel accepts 1…35 mm² rigid or 1…25 mm² flexible cable; tighten to 3.5 N·m. IP20 finger-safe on the body, IP40 inside a modular enclosure. Ambient range -25…60 °C operating, -40…85 °C storage.
