2CCS862001R1557 ABB S802S-UCK40 40A 2-Pole Type K 50kA MCB

Why Choose the ABB S802S-UCK40 High Performance MCB?

The ABB S802S-UCK40 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding commercial and industrial electrical installations. As part of the ABB S800S high-performance circuit breaker series, it combines robust modular construction with current-limiting performance and high fault-current interruption capability.

This circuit breaker features a Type K tripping characteristic and a rated current of 40 A. The Type K characteristic is particularly suitable for circuits supplying motors, transformers and other inductive loads where elevated starting currents can occur, helping reduce unwanted tripping while maintaining dependable protection against overload and short-circuit conditions.

With a high short-circuit breaking capacity of 50 kA, the S802S-UCK40 is engineered for installations where substantial prospective fault currents may occur. Its 2-pole configuration and S800S-UCK design make it a versatile protection device for demanding power distribution, machinery and industrial control applications.
