Why Choose the ABB DDA802 AC-63/0.03 Residual Current Device?
The ABB DDA802 AC-63/0.03 is a two-pole residual current device (RCD) designed to provide residual-current protection in electrical distribution installations. Rated at 63 A with a 30 mA residual operating current, this Type AC device is intended for circuits where detection of sinusoidal alternating residual currents is required.
As part of ABB's DDA800 range, the DDA802 AC-63/0.03 provides residual-current functionality for compatible S800 high-performance circuit-breaker installations. When used in the appropriate ABB system configuration, it complements overcurrent protection by detecting earth-leakage conditions and disconnecting the protected circuit when the residual-current threshold is reached.
The combination of a two-pole configuration, 63 A rated current, 30 mA sensitivity and Type AC residual-current characteristic makes this model suitable for compatible electrical distribution applications requiring sensitive earth-leakage protection. ABB order code 2CSB802001R1630 identifies this specific DDA802 variant.

Reliable Residual-Current Protection for Electrical Distribution
Residual-current protection monitors the balance of current flowing through a circuit and responds when leakage to earth produces a residual current above the device's operating threshold. With a rated residual operating current of 30 mA, the ABB DDA802 AC-63/0.03 provides sensitive detection of applicable AC residual-current faults within a correctly designed electrical installation.
The DDA802 is intended to work as part of ABB's compatible high-performance circuit protection system rather than replacing the overcurrent protection function of the associated circuit breaker. This allows residual-current detection and overload or short-circuit protection to be combined within a coordinated protective arrangement.
Typical Applications
- Electrical distribution systems requiring 30 mA residual-current protection.
- Compatible ABB S800 circuit-breaker installations.
- Commercial electrical distribution boards.
- Industrial electrical distribution equipment.
- Building electrical installations requiring Type AC residual-current detection.
- Circuits requiring residual-current protection alongside compatible overcurrent protection.
