Why Choose the ABB S802S-C50 Miniature Circuit Breaker?

The ABB S802S-C50 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding electrical distribution systems. Part of the ABB S800S high-performance MCB series, it combines a high short-circuit breaking capacity with a Type C tripping characteristic for reliable protection of general-purpose and moderately inductive loads.

With a rated current of 50 A and a short-circuit breaking capacity of 50 kA, the S802S-C50 provides robust circuit protection where high prospective fault currents must be safely interrupted. Its Type C characteristic accommodates moderate starting and switching currents while maintaining effective protection against sustained overloads and short-circuit faults.

The S802S-C50 uses a 2-pole configuration for coordinated protection and switching of two conductors. Its current-limiting construction and high breaking performance make it particularly suitable for industrial distribution systems, machinery, control panels and commercial installations requiring dependable high-performance overcurrent protection.
