It mounts via clip-on to a DIN rail and connects electrically to the matching iC40 MCB by screws, forming a combined RCBO assembly in a 4-pole (3P+N) configuration. The voltage-independent tripping technology means it operates without needing an external power supply — the fault current itself drives the mechanism. The 25 A rated current and 400 V AC operational voltage match the upstream MCB rating; this add-on RCD is sized for outgoing circuits up to that load. Instantaneous tripping provides no intentional delay, so it clears fast — no selectivity with downstream RCDs, but that's the expected behaviour for a final-circuit protector. ## DIN rail integration and wiring The neutral position is left, so orientation matters when assembling the MCB + RCD pair. Terminal connections use tunnel-type terminals: 1…16 mm² rigid or 1…10 mm² flexible, with a wire stripping length of 14 mm for bottom connections.","metaTitle":"Schneider Electric A9Y84725 Acti9 Vigi iC40 RCD, 25A 30mA 4P","metaDescription":"Schneider Electric A9Y84725 Acti9 Vigi iC40 add-on RCD, 25A rated, 30mA sensitivity, Type A-SI, 400V AC, 4P, DIN rail.
