ABB DDA203 RCD, 63A, 3 Pole, 100mA

The ABB RCD block DDA203 series is suitable for assembly with MCBs S200 series. It assures protection against the effects of sinusoidal alternating and direct pulsating earth fault currents with an intentional tripping delay, in order to realize the selectivity with downstream instantaneous devices. The rated current required for this RCD is the 63 A.

Ambient air temperature for operation is -25 to 55 °C
