The ABB S803S-UCB3 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. As part of the ABB S800S high-performance circuit breaker series, it combines a current-limiting design with high fault-current interruption capability for industrial, commercial and electrical distribution applications.
This circuit breaker features a Type B tripping characteristic, a rated current of 3 A and three protected poles. It incorporates two tripping mechanisms: thermal tripping for overload protection and electromagnetic tripping for rapid interruption of short-circuit currents. Fast arc extinction further helps limit the energy released during electrical faults.
With a rated current of 3 A, a three-pole (3P) configuration and a maximum breaking capacity of 50 kA at 240/415 V AC, the S803S-UCB3 provides robust protection for circuits with high prospective fault currents. Its interchangeable cage terminal design supports secure installation and connection within electrical distribution and control equipment.
High-performance miniature circuit breakers such as the ABB S803S-UCB3 automatically interrupt current when dangerous overload or short-circuit conditions occur. The thermal tripping mechanism responds to sustained overloads, while the electromagnetic mechanism provides rapid disconnection during short-circuit faults.
The ABB S800S series is designed for electrical systems where high fault-current interruption capability and effective current limitation are required. The S803S-UCB3 combines three-pole protection, a Type B characteristic, fast arc extinction and a maximum 50 kA breaking capacity to provide dependable protection for industrial distribution and equipment circuits.
