For most domestic and small commercial installations in the UK and Europe, this is sufficient — but if your upstream fault level exceeds 10 kA (e.g., close to a transformer), you need a higher-rated device or a current-limiting upstream MCB. The 30 mA earth-leakage threshold is the standard for additional protection per BS 7671 (18th Edition) — it catches fault currents that could otherwise cause ventricular fibrillation. The thermal-magnetic trip unit handles the overcurrent side; the integrated residual current module handles the leakage side. Both share the same compact 18 mm footprint, so it replaces a separate MCB + RCCD combination in a single DIN-rail slot. IP20 rated — install inside an enclosure, not in washdown areas.","metaTitle":"Schneider Electric A9D37820 IKQE RCBO, 20 A, 30 mA, 10 kA, T","metaDescription":"Schneider Electric A9D37820 Acti9 IKQE RCBO, 20 A rated, 30 mA earth leakage, 10 kA breaking capacity, Type B curve, BS EN 61009-1.
