Why Choose the ABB DS803P-D125/0.3AS RCBO?
The ABB DS803P-D125/0.3AS is a high-performance three-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth-fault currents in demanding electrical installations. Part of the ABB DS800P high-performance circuit protection range, it combines a 125 A rated current, D tripping characteristic and 300 mA Type AS selective residual-current protection.
The Type AS characteristic provides selective residual-current protection with an intentional time delay, supporting coordinated operation with suitable downstream residual-current protective devices. Combined with its D-characteristic overcurrent protection, the DS803P-D125/0.3AS is particularly suitable for industrial circuits where connected equipment can produce substantial starting or inrush currents during normal operation.
With a three-pole configuration, 125 A rated current and 300 mA rated residual operating current, the DS803P-D125/0.3AS provides integrated protection for three-phase electrical systems. Its combined RCBO design brings residual-current and overcurrent protection together in one robust protective device.

Selective Protection for High-Inrush Industrial Circuits
The ABB DS803P-D125/0.3AS combines residual-current monitoring with thermal overload and magnetic short-circuit protection. Integrating these protective functions within one device provides comprehensive protection against earth-fault currents and damaging overcurrent conditions while simplifying the protective arrangement for the connected three-phase circuit.
Its Type AS selective characteristic incorporates delayed residual-current operation to support coordination with appropriately selected downstream residual-current devices. The D tripping characteristic additionally accommodates the higher starting currents associated with suitable motors, transformers and industrial equipment while maintaining protection against overloads and short circuits.
