Why Choose the ABB S804S-K8 High Performance MCB?
The ABB S804S-K8 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution and control applications. As part of the ABB S800S high-performance circuit breaker range, it combines a rated current of 8 A, Type K tripping characteristic and a high short-circuit breaking capability of up to 50 kA.
The S804S-K8 uses thermal and electromagnetic tripping mechanisms to protect circuits and connected equipment against sustained overloads and short circuits. Its Type K characteristic is particularly suited to appropriate loads with elevated starting or inrush currents, including motors, transformers and industrial equipment where reliable operation during normal start-up is required.
With a four-pole configuration, 8 A rated current and short-circuit breaking capability of up to 50 kA, the S804S-K8 provides robust protection for installations where high prospective fault currents may occur. Its four-pole design enables simultaneous protection and switching across four conductors in suitable three-phase distribution, machinery and industrial control applications.
