Why Choose the ABB S801S-B4 High Performance MCB?
The ABB S801S-B4 is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits where a high breaking capacity is required. As part of the ABB S800S high-performance circuit breaker series, it provides robust circuit protection for demanding commercial and industrial electrical installations.
This current-limiting circuit breaker features a Type B tripping characteristic and an interchangeable cage terminal. The S800S platform uses thermal protection against overloads together with electromechanical short-circuit tripping, while rapid arc extinction helps provide dependable interruption of high fault currents.
With a rated current of 4 A and an ultimate short-circuit breaking capacity (Icu) of 50 kA, the S801S-B4 is well suited to low-current circuits requiring high-performance fault protection. ABB order code 2CCF019847R0001 identifies this 4 A, single-pole Type B version of the S800S range.
