Why Choose the ABB S801S-UCK2.5 High Performance MCB?
The ABB S801S-UCK2.5 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-UC high-performance circuit breaker range, it provides dependable protection for demanding industrial and commercial DC electrical installations.
This circuit breaker features a Type K tripping characteristic, a rated current of 2.5 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.
With a rated operational voltage of 250 V DC, one protected pole and a compact DIN-rail format, the S801S-UCK2.5 is designed for demanding direct-current distribution and control applications. Its high fault-current capability and rapid arc extinction provide robust circuit protection in industrial systems.
