Why Choose the ABB S802S-UCK0.5 High Performance MCB?
The ABB S802S-UCK0.5 is a high-performance two-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 protection for demanding commercial and industrial electrical installations.
This circuit breaker features a UC-K / Type K tripping characteristic, a rated current of 0.5 A and an ultimate short-circuit breaking capacity of 50 kA at 500 V DC. The Type K characteristic is particularly suitable for circuits containing inductive loads and equipment with functional starting currents, while the low 0.5 A rating enables protection of sensitive control and auxiliary circuits.
The S802S-UCK0.5 combines a two-pole configuration with ABB's S800S-UC platform dedicated to DC applications. Its high fault-current capability, robust construction and specialised K characteristic make it suitable for demanding systems requiring reliable circuit protection where conventional miniature circuit breakers may not provide sufficient breaking capacity.
