2CCS864002R1135 ABB S804S-UCB13-R 4-Pole 13 A Type B 50 kA Miniature Circuit Breaker

Why Choose the ABB S804S-UCB13-R High-Performance Miniature Circuit Breaker?

The ABB S804S-UCB13-R is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker series, it combines a 13 A rated current, Type B tripping characteristic and high short-circuit breaking capability for industrial and commercial distribution systems.

The S804S-UCB13-R protects circuits against sustained overloads and severe short-circuit faults using thermal and electromagnetic tripping mechanisms. Its current-limiting design helps restrict the fault energy passed through to the installation, reducing thermal and electrodynamic stresses on conductors, connected equipment and downstream components.

With its 4-pole configuration, 13 A current rating and 50 kA short-circuit breaking capacity, the S804S-UCB13-R provides robust protection where high prospective fault currents may occur. The Type B characteristic is suited to circuits with relatively low normal inrush currents, while the R version provides ring-terminal connections.
