Why Choose the ABB DDA204A630.03110V RCD Block?
The ABB DDA204A630.03110V is a four-pole Type A residual current device (RCD) block designed for assembly with compatible ABB miniature circuit breakers. Part of the established ABB DDA200 RCD series, this special 110 V version provides residual current protection for applications requiring a 63 A, 30 mA Type A protection solution.
Rated at 63 A with a rated residual operating current of 30 mA, the DDA204A630.03110V responds to sinusoidal alternating and pulsating DC residual currents. Its high-sensitivity 30 mA characteristic enables additional protection against electric shock when the device is correctly selected and installed in accordance with applicable electrical installation requirements.
The four-pole configuration supports multipole circuit protection, while the dedicated 110 V configuration makes this model suitable where the corresponding DDA200 voltage variant is required. When combined with a compatible ABB miniature circuit breaker, it forms a coordinated solution providing residual-current, overload and short-circuit protection.

High-Sensitivity Type A Residual Current Protection
Residual current protection operates by detecting an imbalance between the current flowing through the conductors of a protected circuit. The Type A characteristic of the ABB DDA204A630.03110V enables detection of sinusoidal alternating residual currents as well as pulsating DC residual currents, providing broader residual-current coverage than a Type AC device.
Its 30 mA operating threshold provides high-sensitivity residual-current protection and can provide additional protection against electric shock where required by the installation design. When assembled with a compatible ABB miniature circuit breaker, the DDA204A630.03110V adds residual-current protection to the overload and short-circuit protection provided by the associated breaker.
