Why Choose the ABB S803S-B10 High Performance MCB?
The ABB S803S-B10 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in residential, commercial and industrial electrical installations. As part of the proven ABB S800S high-performance circuit breaker series, it combines a compact DIN rail format with high current-limiting performance for demanding electrical distribution applications.
This circuit breaker features a Type B tripping characteristic and a rated current of 10 A. Separate thermal and electromechanical tripping mechanisms provide protection against overloads and short circuits respectively, while ABB's rapid arc-extinction technology helps limit fault energy and improve protection of the electrical installation.
With three protected poles and a maximum ultimate short-circuit breaking capacity of 50 kA at 240/415 V AC, the S803S-B10 is suitable for circuits where high fault levels require substantially greater breaking performance than conventional miniature circuit breakers. It supports operating voltages up to 400/690 V AC and is designed for straightforward DIN rail installation in electrical distribution and control equipment.

High-Performance Circuit Protection for Electrical Installations
Miniature circuit breakers protect electrical circuits against excessive current caused by overloads and short circuits. The ABB S803S-B10 uses a thermal tripping mechanism for overload protection together with an electromechanical mechanism that responds rapidly to short-circuit conditions.
The S800S series is engineered for applications requiring high breaking capacity and effective current limitation. The S803S-B10's 50 kA maximum ultimate breaking capacity at 240/415 V AC, rapid arc extinction and three-pole configuration make it particularly suitable for three-phase distribution systems and industrial installations where prospective fault currents can be high.
Typical Applications
- Three-phase electrical distribution systems.
- Industrial control panels and switchboards.
- Commercial electrical distribution installations.
- Industrial machinery and automation systems.
- Branch circuit overload and short-circuit protection.
- Installations requiring high short-circuit breaking capacity.
