ABB S801S-B4 is a 4 A single-pole Type B high-performance miniature circuit breaker with 50 kA ultimate short-circuit breaking capacity for overload and short-circuit protection.
£65.34
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.
Miniature circuit breakers automatically interrupt electrical current when an overload or short circuit occurs, helping protect conductors, equipment and electrical installations from damaging fault conditions. The ABB S800S range is designed for applications requiring particularly high short-circuit interruption performance and reliable current limitation.
The S801S-B4 combines a 4 A current rating with a Type B characteristic in a compact single-pole device. Its high breaking capacity, rapid arc extinction and robust S800S construction make it suitable for demanding distribution, control and industrial applications where dependable protection is essential.
