ABB S802N-B50 is a 50 A Type B 2-pole high-performance miniature circuit breaker with a 36 kA ultimate short-circuit breaking capacity at 415 V AC for demanding commercial and industrial circuit protection.
£114.02
The ABB S802N-B50 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. As part of the ABB S800N high-performance MCB range, it combines a compact DIN rail format with high short-circuit breaking capacity for dependable circuit protection.
Featuring a 50 A rated current and Type B tripping characteristic, the S802N-B50 provides thermal protection against overloads together with electromagnetic protection against short circuits. Its current-limiting design makes it particularly suitable for installations where high prospective fault currents require greater breaking performance than conventional miniature circuit breakers.
The S802N-B50 provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC according to IEC/EN 60947-2, with a rated service short-circuit breaking capacity of 30 kA at 415 V AC. Its two protected poles, screw terminals and robust construction make it suitable for industrial distribution boards, commercial installations, machinery and other electrical systems requiring high-performance circuit protection.
Miniature circuit breakers such as the ABB S802N-B50 automatically interrupt an electrical circuit when excessive current occurs because of an overload or short circuit. The thermal tripping mechanism provides overload protection, while the electromagnetic tripping mechanism responds rapidly to short-circuit conditions to protect cables, equipment and the wider electrical installation.
The ABB S800N range is designed for commercial and industrial installations requiring high breaking capacity. With an Icu rating of 36 kA at 415 V AC, the S802N-B50 provides robust protection where high prospective short-circuit currents are present and can be used in applications requiring selectivity or back-up protection arrangements.
