It is a 3P+N unit rated 40 A at 400 V AC phase-to-phase, with Type A-SI (Super Immunised) sensitivity that resists nuisance tripping from high-frequency harmonics or transient surges common on modern electronic loads. Mounts via clip-on to DIN rail, occupies 6 x 9 mm pitches (54 mm width), and connects to the upstream MCB by screws through the cable terminals (accepts 0.75–16 mm² rigid or 0.33–10 mm² flexible). ## Lifecycle status and sourcing reality The A9N21496 is marked obsolete by Schneider Electric. 40 A rated current (In) and 30 mA earth-leakage sensitivity make this a group-incomer or sub-distribution RCD for a 3-phase + neutral circuit feeding mixed loads. Voltage-independent trip technology means the RCD operates without needing a separate power supply; it uses the fault energy itself to open the contacts. Rated insulation voltage 400 V AC, impulse withstand 6 kV, pollution degree 3, and tropicalisation class 2 per IEC 60068-1. IP20 finger-safe terminals — intended for enclosed panel mounting, not washdown environments. Designed and tested to IEC 60947-2, EN 61009-1, and EN 61009-2-1. The EN 61009 series covers residual current operated circuit-breakers with integral overcurrent protection — this add-on block is the RCD element intended to pair with a compatible MCB to form a complete RCBO assembly.","metaTitle":"Schneider Electric A9N21496 Vigi TG40 40A 30mA RCD, Obsolete","metaDescription":"Schneider Electric A9N21496 Prodis Vigi TG40 add-on RCD, 40A 30mA, 3P+N, Type A-SI.
