Why Choose the ABB S804C-D25 High Performance MCB?
The ABB S804C-D25 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the advanced ABB S800C high-performance circuit breaker series, it combines high breaking capacity, effective current limitation and robust construction for residential, commercial and industrial applications.
This circuit breaker features a D tripping characteristic and a rated current of 25 A, making it particularly suitable for circuits supplying equipment with high starting or inrush currents. It incorporates separate thermal and electromechanical tripping mechanisms to provide reliable overload and short-circuit protection.
With four protected poles and an ultimate short-circuit breaking capacity of 25 kA at 240/415 V AC, the S804C-D25 is designed for installations where substantial prospective fault currents may occur. Its current-limiting design and fast arc extinction help reduce fault energy and protect downstream electrical equipment.
