Why Choose the ABB S803N-C50 Miniature Circuit Breaker?
The ABB S803N-C50 is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the ABB S800N high-performance circuit breaker series, it combines a rated current of 50 A, Type C tripping characteristic and a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC for demanding commercial and industrial applications.
The Type C characteristic makes the S803N-C50 suitable for circuits with moderate starting and inrush currents, including machinery, control equipment and general industrial loads. Its thermal-magnetic operating principle provides dependable overload and short-circuit protection, while the three-pole configuration enables simultaneous protection and switching of all three phases.
With a 50 A rated current, 3-pole configuration and high fault-current capability, the S803N-C50 is well suited to three-phase distribution and equipment circuits. The breaker uses cage terminals and a DIN-rail format for straightforward integration into electrical switchboards, distribution assemblies and industrial control panels.
