The Schneider Electric A9R71463S is a 4-pole Acti9 iID residual current circuit breaker (RCCB) rated for 63 A continuous load and 30 mA earth-leakage sensitivity. The 30 mA threshold is the standard for personal shock protection in residential and commercial final circuits — it trips fast enough to prevent ventricular fibrillation under fault conditions. Breaking and making capacity is rated at Idm 1500 A / Im 1500 A. The impulse withstand rating is 250 A (8/20 µs waveform) per EN/IEC 61008-1. Insulation voltage is 500 V AC, and impulse withstand voltage is 6 kV.
Deployment context
Clip-on mounting on a DIN rail, 72 mm wide (8 x 9 mm pitches), neutral on the left — standard for European panel layouts.
