Why Choose the ABB S803S-C6 High Performance MCB?
The ABB S803S-C6 is a high-performance 3-pole miniature circuit breaker (MCB) designed for demanding industrial circuit protection. Part of the ABB S800S high-performance range, it combines a 6 A rated current, Type C tripping characteristic and a maximum 50 kA breaking capacity at 240/415 V AC.
The S803S-C6 is a current-limiting circuit breaker with separate thermal and electromechanical tripping mechanisms. The thermal mechanism provides overload protection, while the electromechanical mechanism responds rapidly to short-circuit conditions. ABB's fast arc-extinction technology helps limit fault energy and protect connected equipment.
With 3 protected poles, a 6 A rated current and Type C characteristic, the S803S-C6 is suitable for industrial distribution and equipment circuits with moderate functional inrush currents. Its cage-terminal construction, AC/DC capability and compliance with IEC/EN 60947-2, IEC/EN 60898-1 and UL 1077 make it a versatile high-performance protection device.
