Why Choose the ABB S804S-B25 High Performance MCB?
The ABB S804S-B25 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 25 A, Type B tripping characteristic and a high short-circuit breaking capability of up to 50 kA.
The S804S-B25 uses thermal and electromagnetic tripping mechanisms to protect circuits and connected equipment against sustained overloads and short circuits. Its Type B characteristic provides a sensitive magnetic trip response suited to circuits with relatively low starting or inrush currents, making it appropriate for suitable resistive loads, control equipment and general electrical distribution applications.
With a four-pole configuration, 25 A rated current and short-circuit breaking capability of up to 50 kA, the S804S-B25 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 and industrial electrical systems.
