Why Choose the ABB S803S-UCK2 High Performance MCB?
The ABB S803S-UCK2 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect direct-current 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 robust 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 at 750 V DC. The Type K characteristic is suited to circuits with functional starting or inrush currents, making the S803S-UCK2 particularly useful for industrial control, auxiliary and inductive-load applications.
The S803S-UCK2 combines a three-pole configuration with ABB's S800S-UC platform for DC applications. Its high fault-current capability, interchangeable cage terminals and Type K characteristic make it suitable for demanding systems requiring reliable protection while accommodating the operating characteristics of inductive equipment.
