Why Choose the ABB S803S-UCB16-R High Performance MCB?
The ABB S803S-UCB16-R is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB S800S high-performance MCB series, it combines a 16 A rated current, Type B tripping characteristic and high short-circuit breaking capacity for demanding industrial and commercial electrical installations.
This circuit breaker provides dependable protection for cables and electrical equipment while offering a 50 kA breaking capacity. Its Type B characteristic is suited to circuits with relatively low starting and inrush currents, providing responsive protection for appropriate distribution, control and resistive-load applications.
With a rated current of 16 A and a three-pole configuration, the S803S-UCB16-R provides coordinated protection across three conductors. The R version features ring-terminal connection, providing secure termination for installations using ring cable lugs.
