Why Choose the ABB S801S-UCK80-R Miniature Circuit Breaker?
The ABB S801S-UCK80-R is a high-performance single-pole miniature circuit breaker (MCB) designed for protection and control of demanding electrical circuits against overloads and short circuits. As part of the ABB S800S-UC range, this specialised version combines a Type K tripping characteristic, high short-circuit breaking capacity and ring-terminal connection for professional DC circuit protection.
With a rated current of 80 A and an ultimate short-circuit breaking capacity of 50 kA, the S801S-UCK80-R provides robust protection where high prospective fault currents may occur. Its Type K characteristic is particularly suitable for circuits such as motors, transformers and auxiliary circuits, helping prevent nuisance tripping from functional peak currents while providing sensitive thermal overload protection.
The S801S-UCK80-R is a 1-pole breaker specifically designed for direct-current applications and features a ring-terminal connection arrangement. Its combination of high breaking performance, current-limiting operation and specialised DC design makes it suitable for demanding commercial, industrial and transportation electrical systems.

High-Performance Protection for DC Electrical Circuits
High-performance circuit breakers such as the ABB S801S-UCK80-R use thermal and electromagnetic tripping principles to protect circuits against overload and short-circuit conditions. The S800S-UCK range is specifically designed for direct-current applications where high breaking capacity is required, including motor, transformer and auxiliary circuits.
The Type K characteristic helps prevent nuisance tripping when functional peak currents occur while its sensitive thermal protection helps protect cables, lines and connected equipment against damaging overcurrents. The S801S-UCK80-R can also support appropriately engineered selectivity with upstream MCCBs or back-up protection arrangements for downstream MCBs.
Typical Applications
- Industrial direct-current distribution systems.
- Motor and transformer circuit protection.
- Auxiliary and control circuits.
- Transportation and rolling-stock electrical systems.
- Commercial and industrial DC installations.
- Circuits requiring high short-circuit breaking capacity.
