Why Choose the ABB DS802P-D125/0.3AS RCBO?
The ABB DS802P-D125/0.3AS is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults in demanding industrial electrical installations. As part of the ABB DS800P series, it combines a rated current of 125 A, D tripping characteristic and selective Type AS residual current protection in a single protective device.
This RCBO provides overload and short-circuit protection together with residual current protection for AC and pulsating DC earth fault currents. Its selective residual current operation incorporates an intentional time delay, supporting discrimination with suitable downstream residual current protective devices and helping improve continuity of supply in coordinated installations.
With a rated residual operating current of 300 mA and an ultimate short-circuit breaking capacity of 50 kA to IEC/EN 60947-2, the DS802P-D125/0.3AS is engineered for industrial circuits where high fault-current capability, selective earth fault protection and tolerance of elevated inrush currents are required.

Selective Protection for High-Inrush Industrial Circuits
RCBOs combine residual current protection with overload and short-circuit protection in a single device. This integrated approach simplifies electrical protection arrangements while helping protect circuits, equipment and installations against multiple common fault conditions.
The D tripping characteristic makes the DS802P-D125/0.3AS particularly suitable for circuits containing equipment with relatively high starting or inrush currents. Combined with selective Type AS residual current operation, the device supports coordinated protection in demanding industrial distribution systems.
