The 30 mA sensitivity covers standard personnel protection against direct contact, while the Type A-SI (Super Immunised) classification means it resists nuisance tripping from high-frequency leakage or pulsed DC waveforms — common on variable-speed drives, UPS systems, or LED lighting circuits that generate smooth DC fault currents a standard Type A might miss. Tunnel terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible cable, tightened to 2 N·m. At 74 mm deep and 95 mm tall, it fits standard modular enclosures with IP40 protection in the enclosure (IP20 on the terminals). The white housing matches the Acti9 family aesthetic for panel builders who care about visual consistency. ## Electrical and environmental limits Rated insulation voltage is 400 V AC, with an impulse withstand of 4 kV per EN/IEC 61009-2-1. Relative humidity tolerance is 95% at 55 °C. Maximum operating altitude is 2000 m.","metaTitle":"Schneider Electric A9Y84640 Vigi iC40 40A 30mA RCD, Type A-S","metaDescription":"Schneider Electric A9Y84640 Acti9 Vigi iC40 add-on RCD, 40A rated, 30mA sensitivity, Type A-SI super immunised, 1P+N, DIN rail.

It's a step up from standard Type A for modern non-linear loads."},{"question":"What MCB does A9Y84640 clip onto?","answer":"It's designed as an add-on for the Acti9 iC40 range of MCBs.
