Why Choose the ABB S803S-D8 High-Performance MCB?
The ABB S803S-D8 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 installations. Part of the established ABB S800S high-performance circuit breaker series, it combines an 8 A rated current with a powerful 50 kA short-circuit breaking capacity.
Featuring a Type D tripping characteristic, the S803S-D8 is particularly suited to circuits supplying equipment with high starting or inrush currents. Its thermal-magnetic protection provides dependable overload and short-circuit protection while allowing the temporary current peaks associated with loads such as motors, transformers and other inductive equipment.
With its three-pole configuration, 8 A rated current and 50 kA breaking capacity, the S803S-D8 provides robust protection for three-phase machinery, distribution and industrial power circuits. Its modular construction supports straightforward integration into electrical distribution boards and control assemblies.

High-Performance Protection for Three-Phase Circuits
High-performance circuit breakers such as the ABB S803S-D8 automatically disconnect electrical circuits when excessive current results from overload or short-circuit conditions. Thermal protection responds to sustained overloads, while magnetic protection provides rapid interruption when severe fault currents occur.
The Type D characteristic is designed for applications where normal operation can produce substantial temporary inrush currents. Combined with the S803S-D8's 50 kA breaking capacity, this makes the breaker particularly suitable for demanding three-phase industrial circuits containing motors, transformers and other equipment with high starting-current requirements.
Typical Applications
- Three-phase industrial electrical distribution systems.
- Industrial motors and machinery.
- Transformer and inductive-load circuits.
- Production and manufacturing equipment.
- Commercial and industrial switchboards.
- Installations requiring high short-circuit breaking capacity.
