Why Choose the ABB S804S-UCK25-R High Performance MCB?
The ABB S804S-UCK25-R is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance MCB series, it combines high breaking capacity with reliable thermal and electromagnetic protection for industrial and commercial applications.
Featuring a Type K tripping characteristic and rated current of 25 A, the S804S-UCK25-R is particularly suited to circuits supplying equipment with elevated starting or inrush currents. The K characteristic makes it a practical choice for applications such as motors, transformers and other inductive loads where unwanted tripping during normal starting conditions must be minimised.
With a specified short-circuit breaking capacity of 50 kA, the S804S-UCK25-R provides robust protection for installations with high prospective fault currents. Its current-limiting construction and rapid arc-extinction system help reduce fault energy and electrical stress on downstream equipment while the four-pole design provides coordinated multi-pole circuit protection.

High-Performance Protection for Inductive Loads
The ABB S800S range is engineered for installations requiring high fault-breaking performance and dependable circuit protection. The S804S-UCK25-R combines thermal overload protection with fast electromagnetic short-circuit tripping while providing coordinated switching across four poles.
Its Type K characteristic is designed to tolerate the elevated starting currents associated with motors, transformers and other inductive equipment while still responding rapidly to damaging short-circuit currents. This makes the S804S-UCK25-R particularly useful in industrial systems where both high breaking capacity and resistance to nuisance tripping are important.
Typical Applications
- Industrial motor circuits.
- Transformers and inductive loads.
- Machinery and automation control panels.
- Industrial electrical distribution boards.
- Circuits with elevated starting or inrush currents.
- High fault-level commercial and industrial installations.
