Why Choose the ABB S804P-C125 High Performance MCB?

The ABB S804P-C125 is a robust four-pole high performance miniature circuit breaker (MCB) designed to protect demanding industrial and commercial electrical installations against overloads and short circuits. Part of the advanced ABB S800P circuit breaker series, it combines a high rated current with exceptional fault interruption performance.

This circuit breaker features a C tripping characteristic, making it suitable for circuits containing equipment with moderate inrush currents. Its dependable thermal-magnetic protection helps safeguard cables, machinery and electrical distribution equipment while reducing the risk of damage caused by abnormal current conditions.

With a rated current of 125 A, a four-pole configuration and an ultimate short-circuit breaking capacity of up to 50 kA at 240/415 V AC, the S804P-C125 is ideal for high-demand power distribution, industrial switchboards and machine control systems. Its compact rail-mounted construction enables straightforward integration into professional electrical panels.
