Why Choose the ABB DDA803 A-63/0.03 AP-R RCD Block?
The ABB DDA803 A-63/0.03 AP-R is a high-performance three-pole Type A AP-R residual current device (RCD) block designed for combination with compatible ABB S800 miniature circuit-breakers. As part of the ABB DDA 800 series, it provides sensitive residual current protection for commercial and industrial electrical distribution systems.
ABB's AP-R high-immunity characteristic combines Type A residual current detection with enhanced resistance to unwanted tripping caused by transient disturbances. It detects sinusoidal alternating and pulsating direct residual currents, making it suitable for modern installations containing electronic equipment while helping maintain continuity of service.
With a rated current of 63 A, a rated residual operating current of 30 mA and a three-pole configuration, the DDA803 A-63/0.03 AP-R provides sensitive earth fault protection for compatible distribution circuits. When assembled with a suitable ABB S800 MCB, it adds residual current protection to the overload and short-circuit protection provided by the associated circuit-breaker.
