It is rated 25 A with 300 mA sensitivity, instantaneous trip, and is designed for 400 V AC phase-to-phase networks at 50 Hz. The 25 A rated current (In) and 300 mA earth-leakage sensitivity are matched for group incomer or sub-distribution board protection where a higher leakage threshold is acceptable — typically for circuits feeding multiple loads where nuisance tripping from cumulative leakage is a concern. Type A detection covers pulsating DC residual currents, which standard AC-only RCDs miss; this matters for circuits with rectified loads like switching power supplies or variable-speed drives. The voltage-independent trip technology means the RCD operates without needing a separate power supply, so it clears leakage faults even if the line voltage collapses. The instantaneous time delay (no intentional delay) means it trips within the standard RCD response window — suitable for direct shock protection in final circuits, but coordination with downstream RCDs needs care to avoid nuisance tripping on transient leakage. The add-on block screws directly to the MCB body — no extra wiring for the leakage detection circuit. Dimensions are 54 mm wide, 82 mm high, 70 mm deep, occupying six 9 mm pitches on the rail.","metaTitle":"Schneider A9N21760 Vigi DPNc RCD Add-On, 25A 300mA Type A, O","metaDescription":"Schneider A9N21760 Vigi DPNc add-on RCD, 3P+N, 25A, 300mA Type A, instantaneous.
