Why Choose the ABB DDA202 A-40/0.03 RCD Block?
The ABB DDA202 A-40/0.03, order code 2CSB202101R1400, is a compact 2-pole Type A residual current device (RCD) block designed for coupling 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 highly sensitive 30 mA rated residual operating current. When coupled 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 2-pole configuration, 50–60 Hz rated frequency and compact modular construction, the DDA202 A-40/0.03 is designed for straightforward integration into electrical distribution boards. Its 30 mA sensitivity and Type A characteristic make it particularly suitable for modern circuits containing electronic equipment capable of producing pulsating DC residual currents.
