Why Choose the ABB S804S-B8 High Performance MCB?
The ABB S804S-B8 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial and commercial electrical installations. As part of the ABB S800S high-performance circuit breaker series, it combines an 8 A rated current, Type B tripping characteristic and high breaking capacity for dependable circuit protection.
The S804S-B8 is engineered for applications where high fault levels require greater breaking performance than conventional miniature circuit breakers. Its 50 kA rated ultimate short-circuit breaking capacity provides robust protection for electrical distribution systems, machinery and control equipment.
With four protected poles and an 8 A rated current, the S804S-B8 is suitable for multi-pole AC circuits requiring simultaneous isolation and protection. Its Type B characteristic is well suited to circuits with relatively low inrush currents, including resistive loads, control circuits and general electrical distribution applications.
