Why Choose the ABB DDA202 A-40/0.3 RCD Block?
The ABB DDA202 A-40/0.3, order code 2CSB202101R3400, 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 applications requiring detection of both sinusoidal alternating and pulsating DC residual currents.
This Type A RCD block has a 40 A rated current and a 300 mA rated residual operating current. When assembled with a compatible ABB miniature circuit breaker, the DDA200 arrangement combines residual current protection with the overcurrent and short-circuit protection provided by the associated circuit breaker.
With its 2-pole configuration, Type A residual current characteristic and modular construction, the DDA202 A-40/0.3 provides a practical solution for residential, commercial and industrial distribution systems. Its 300 mA residual current rating makes it suitable for applications where earth leakage and fault protection are required at this operating threshold.
