Rated at 25 A (In) with 30 mA sensitivity, Type AC earth-leakage protection, and instantaneous trip. The voltage-independent trip mechanism means it operates without needing an external power supply — it draws its trip energy from the fault current itself. Certified to IEC 60947-2, EN 61009-1, and EN 61009-2-1. Pollution degree 3 per EN 61009-1, impulse withstand voltage 6 kV (Uimp), and tropicalisation class 2 per IEC 60068-1 — suitable for controlled indoor environments with high humidity (95% at 55 °C). The 25 A rated current and 30 mA sensitivity are the key specs. The 25 A In matches the upstream MCB rating — this RCD block is sized for a group incomer. Type AC detection means it trips on sinusoidal AC residual currents only. Rated operational voltage 400 V AC phase-to-phase, 50 Hz. Insulation voltage 400 V AC. The 3P+N configuration with neutral on the left (viewed from the front) must be observed when wiring — reversing the neutral and a phase compromises the trip coil supervision. Clip-on mounting to DIN rail, 6 module pitches wide (54 mm). IP20 finger-safe front, but the terminals require live-work precautions when the enclosure door is open.","metaTitle":"Schneider Electric A9N21490 Vigi TG40 RCD, 25A 30mA 3P+N","metaDescription":"Schneider Electric A9N21490 Vigi TG40 add-on RCD, 25A rated current, 30mA sensitivity, 3P+N, 400V AC.
