Why Choose the ABB S803S-B10-R High-Performance MCB?
The ABB S803S-B10-R is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding industrial and commercial power distribution systems. As part of the ABB S800S high-performance circuit breaker series, it combines a 10 A rated current, Type B tripping characteristic and a high 50 kA short-circuit breaking capacity.
The Type B characteristic provides sensitive magnetic tripping for circuits with relatively low starting or inrush currents. This makes the S803S-B10-R suitable for resistive loads, distribution circuits and equipment where rapid response to fault currents is required. Thermal and electromagnetic tripping mechanisms provide dependable protection against sustained overload conditions and high-current short-circuit faults.
Its three-pole construction enables coordinated protection and switching of three-phase circuits. The S803S-B10-R is designed for professional industrial distribution, machinery and control-panel applications where robust construction, high fault-current capability and reliable overcurrent protection are required.

Reliable Protection for Low-Inrush Three-Phase Circuits
High-performance miniature circuit breakers such as the ABB S803S-B10-R automatically disconnect electrical circuits when current exceeds permitted operating limits. The thermal element responds to sustained overload conditions, while the electromagnetic mechanism rapidly interrupts high-current short circuits to help protect conductors, connected equipment and electrical distribution infrastructure.
The Type B characteristic provides relatively sensitive magnetic operation, making the S803S-B10-R particularly appropriate for circuits where substantial starting currents are not normally expected. Combined with the S800S platform's 50 kA breaking capacity and three-pole construction, it provides dependable protection for demanding three-phase industrial and commercial systems.
