Why Choose the ABB S803S-B6 High Performance MCB?
The ABB S803S-B6 is a high-performance 3-pole miniature circuit breaker (MCB) designed for demanding commercial and industrial circuit protection. Part of the ABB S800S high-performance range, it combines a 6 A rated current, Type B tripping characteristic and a high 50 kA breaking capacity for installations with substantial prospective short-circuit currents.
The S803S-B6 is a current-limiting circuit breaker incorporating thermal overload protection and electromagnetic short-circuit protection. Its Type B characteristic provides sensitive magnetic operation, making it well suited to circuits with relatively low inrush currents as well as applications where rapid fault response is required.
With 3 protected poles, a 6 A rated current and Type B characteristic, the S803S-B6 provides simultaneous protection for three-phase circuits. Its high-performance S800S construction makes it suitable for industrial distribution, machinery, control equipment and other installations requiring dependable overload and short-circuit protection.
