Why Choose the ABB DDA202 A-63/0.03 RCD Block?
The ABB DDA202 A-63/0.03, order code 2CSB202101R1630, is a compact 2-pole Type A residual current device (RCD) block designed for assembly with compatible ABB miniature circuit breakers to provide residual current protection in low-voltage electrical installations. As part of the ABB DDA200 RCD series, it is suitable for residential, commercial and industrial applications requiring protection against sinusoidal alternating and pulsating DC earth fault currents.
This Type A RCD block has a 63 A rated current and a highly sensitive 30 mA rated residual operating current. When assembled with a compatible ABB miniature circuit breaker, the DDA200 system combines residual current protection with the overcurrent and short-circuit protection provided by the associated circuit breaker.
With a 230/400 V AC rated voltage, instantaneous operating characteristic and robust modular construction, the DDA202 A-63/0.03 provides a dependable solution for modern electrical distribution systems. Its 30 mA sensitivity provides additional protection against direct contact, while its Type A characteristic enables detection of residual currents associated with many modern electronic loads.
