2CCS883001R0254 ABB S803C-C25 Miniature Circuit Breaker 25 A 3P Type C 25 kA

Why Choose the ABB S803C-C25 Miniature Circuit Breaker?

The ABB S803C-C25 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the ABB S800C high-performance circuit breaker series, it combines high breaking capacity with current-limiting performance for demanding commercial and industrial electrical installations.

This MCB features a Type C tripping characteristic, making it suitable for general-purpose circuits and equipment with moderate starting or inrush currents. Its thermal tripping mechanism provides overload protection, while its electromechanical short-circuit mechanism provides rapid fault protection.

With a rated current of 25 A, a three-pole configuration and a rated ultimate short-circuit breaking capacity of 25 kA, the S803C-C25 provides robust protection for three-phase electrical systems where substantial prospective fault currents may occur. Its S800C construction makes it well suited to industrial switchgear, machinery, control panels and distribution assemblies.
