2CCF019982R0001 ABB S801S-UCK2 MCB 50 kA 1P Type K 2 A

Why Choose the ABB S801S-UCK2 High Performance MCB?

The ABB S801S-UCK2 is a high-performance single-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 high-performance circuit breaker range, it provides dependable circuit protection for demanding commercial and industrial electrical installations.

This circuit breaker features a UC-K / Type K tripping characteristic, a rated current of 2 A and an ultimate short-circuit breaking capacity of 50 kA. The Type K characteristic is particularly suitable for circuits supplying motors, transformers and other inductive loads where functional peak currents can occur during normal operation.

The S801S-UCK2 belongs to ABB's S800S-UC range for direct-current circuit applications. Its single-pole configuration and high fault-current capability make it suitable for industrial installations requiring reliable overload and short-circuit protection, selectivity or coordinated back-up protection.
