It handles a rated current of 63 A and trips at 500 mA residual current, type AC (sensitive to sinusoidal AC fault currents only).
Rated at 63 A continuous, this RCD pairs with a 63 A or lower-rated MCB upstream; exceeding that continuous current risks nuisance tripping from thermal effects in the RCD itself. The 500 mA trip threshold is higher than the typical 30 mA for personal shock protection — it is sized for equipment protection or fire prevention where some leakage is expected (e.g., long cable runs, industrial heaters). Type AC detection covers sinusoidal AC faults only; if the load includes rectifiers, VFDs, or switched-mode supplies that generate pulsed DC fault currents, a type A RCD would be needed instead.
Installation depth is 70 mm, matching the 5SY breaker it clips onto. The fastening method is REG (regular DIN-rail clip).
Insulation voltage (Ui) is 460 V, surge voltage resistance 4 kV, overvoltage category III, pollution degree 2 — suitable for fixed-installation distribution boards in normal indoor environments. Supply frequency is 50 Hz only.
