Why Choose the ABB DDA202 A-63/0.3 RCD Block?
The ABB DDA202 A-63/0.3, order code 2CSB202101R3630, 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 provides protection against sinusoidal alternating and pulsating DC earth fault currents in residential, commercial and industrial applications.
This Type A RCD block has a 63 A rated current and a 300 mA rated residual operating current. When assembled with a compatible ABB S200 series miniature circuit breaker, the DDA200 arrangement 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, 50–60 Hz rated frequency and instantaneous operating characteristic, the DDA202 A-63/0.3 provides a dependable modular solution for electrical distribution systems. Its Type A characteristic makes it suitable for circuits where sinusoidal AC and pulsating DC residual currents may occur.
