Type A Differential Circuit Breaker 63A 30mA 400V 3P+N, suitable for family homes, small commercial buildings and other scenarios

This is a Type A Residual Current Circuit Breaker (RCCB/RCD) which provides protection against residual AC and pulsed residual direct current ground leaks. This type A RCD incorporates all the characteristics of the AC type while providing additional protection against pulsed DC residual currents. In the event of electric shock or leakage, the RCD will cut off the faulty circuit in less than 0.1 seconds, thus protecting people's safety and preventing fire caused by damage to insulation. Rated current 63A, rated voltage 400V AC, with differential protection 30mA (instant trigger ≤0.1s) and |nc = |△c = 6kA. Please note that Type A RCD does not detect smooth continuous residual currents (e.g. continuous components in PV systems or EV charging batteries). For the detection of these residual currents, please use the type B RCD
