2CCF019992R0001 ABB S802S-UCB2 MCB 50 kA 2P Type B 2 A

Why Choose the ABB S802S-UCB2 High Performance MCB?

The ABB S802S-UCB2 is a high-performance two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits where a high breaking capacity is required. As part of the ABB S800S-UC high-performance circuit breaker range, it provides dependable circuit protection for demanding commercial and industrial electrical installations.

This circuit breaker features a UC-B / Type B tripping characteristic, a rated current of 2 A and an ultimate short-circuit breaking capacity of 50 kA. The Type B characteristic provides sensitive protection for circuits where substantial functional inrush currents are not normally expected, making this low-current MCB suitable for control, auxiliary and other sensitive electrical circuits.

The S802S-UCB2 combines a two-pole configuration with ABB's S800S-UC platform for direct-current applications. Its high fault-current capability and low rated current make it suitable for demanding systems requiring reliable overload and short-circuit protection, selectivity or coordinated back-up protection.
