Why Choose the ABB S402M-K2 Miniature Circuit Breaker?
The ABB S402M-K2 is a current-limiting miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for low-current circuits in commercial, industrial and critical power distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines dependable two-pole protection with the modular plug-in architecture of the SMISSLINE TP system.
The breaker uses thermal and electromagnetic tripping to protect wiring and connected equipment against overcurrents. Its Type K tripping characteristic is particularly suited to compatible inductive loads and circuits where higher starting currents may occur.
With a rated current of 2 A, a rated voltage of 240 V AC and a 10 kA short-circuit breaking capacity, the S402M-K2 provides precise protection for low-current two-pole circuits. Its SMISSLINE TP plug-in design enables straightforward integration into compatible ABB modular distribution systems.
