2CCS891001R0254 ABB S801N-C25 High Performance MCB 36 kA 1P Type C 25 A

Why Choose the ABB S801N-C25 High Performance MCB?

The ABB S801N-C25 is a high-performance single-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800N high-performance circuit breaker series, it combines high breaking capacity, effective current limitation and robust construction for commercial and industrial electrical installations.

This circuit breaker features a C tripping characteristic and a rated current of 25 A, making it suitable for general-purpose circuits and equipment with moderate starting or inrush currents. Thermal tripping provides overload protection, while an electromechanical release provides rapid protection against short-circuit faults.

With a single protected pole and a high short-circuit breaking capacity of 36 kA, the S801N-C25 is designed for installations where substantial prospective fault currents may occur. Its current-limiting operation and rapid arc extinction help reduce let-through fault energy and the associated thermal and mechanical stresses on electrical equipment.
