2CCS862001R1805 ABB S802S-UCB80 High Performance MCB 50 kA 2P Type B 80 A

Why Choose the ABB S802S-UCB80 High Performance MCB?

The ABB S802S-UCB80 is a high-performance 2-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 range, this model combines a rated current of 80 A with a Type B tripping characteristic, making it suitable for appropriately designed circuits with relatively low starting and inrush currents.

The S802S-UCB80 uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment. Its thermal mechanism responds to sustained overload conditions, while the electromagnetic mechanism provides rapid interruption during short-circuit faults. With a high 50 kA short-circuit breaking capacity, the breaker is designed for installations where substantial prospective fault currents demand high-performance protection.

With its two-pole configuration, 80 A rated current and robust modular construction, the S802S-UCB80 is suited to industrial distribution boards, machinery, control panels and commercial electrical systems. The ABB S800 platform provides high current-limiting performance and supports integration with compatible auxiliary and signalling accessories for flexible panel design.
