Why Choose the ABB S804S-B20-R High Performance MCB?
The ABB S804S-B20-R 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 a 20 A rated current, Type B tripping characteristic and high breaking capacity for dependable circuit protection.
The S804S-B20-R is engineered for applications where high prospective fault currents require greater breaking performance than conventional miniature circuit breakers. Its 50 kA short-circuit breaking capacity makes it suitable for robust electrical distribution systems, machinery and control equipment where reliable fault interruption is essential.
With four protected poles and a 20 A rated current, the S804S-B20-R provides multi-pole protection for electrical circuits. Its Type B characteristic is suited to circuits with relatively low starting and inrush currents, including resistive loads, control circuits and general electrical distribution applications.
