Tripping is instantaneous and voltage-independent — the fault current itself powers the trip mechanism, so it works even if the neutral is lost upstream. That makes it a robust choice for group protection where you cannot rely on the supply voltage being present at the moment of fault. The 40 A In rating matches a 40 A MCB upstream — the RCD must be paired with a breaker of equal or lower rating. Type A covers the mixed AC and pulsed DC waveforms common from variable-speed drives, LED drivers, and switched-mode power supplies. Rated operational voltage is 400 V AC at 50/60 Hz, with insulation rated at 440 V and impulse withstand at 4 kV per EN/IEC 61009-2-1. The IP20 body protects against finger contact; the modular enclosure achieves IP40 when mounted in a board. Clip-on mounting to DIN rail, 6 modules wide at 9 mm pitch (108 mm total width). Operating temperature range is -25 to 60 °C, storage -40 to 85 °C, with 95 % relative humidity at 55 °C. Maximum operating altitude 2000 m. The white body carries a local fault-indication window for quick visual inspection on the panel door.","metaTitle":"Schneider Electric A9Y71740 Acti9 Vigi iCG40 RCD, 40A 300mA","metaDescription":"Schneider Electric A9Y71740 Acti9 Vigi iCG40 add-on residual current device. 40 A rated, 300 mA Type A sensitivity, 3P+N, 400 V AC.
