Why Choose the ABB S401P-K25 Miniature Circuit Breaker?
The ABB S401P-K25 is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines a 25 A rated current, K tripping characteristic and high short-circuit breaking capacity for demanding industrial and commercial electrical distribution applications.
Designed for direct integration with the SMISSLINE TP plug-in system, the S401P-K25 provides a modular alternative to conventionally wired protective devices. Its plug-in construction supports efficient installation, replacement and expansion of distribution assemblies while ABB's thermal and electromagnetic tripping technology provides dependable protection against overloads and short circuits.
With a rated current of 25 A and an ultimate short-circuit breaking capacity (Icu) of 30 kA, the S401P-K25 is suitable for circuits where substantial prospective fault currents and elevated starting currents may occur. Its compact single-pole design occupies just one module within the SMISSLINE TP system.
