MCB Icn=10000A / Icu=15kA 3P C 25A NCN325

The miniature circuit breaker marked as Icn=10000A / Icu=15kA 3P C 25A is an electrical device that plays a key role in protecting installations from the effects of overloads and short circuits. Its main task is to automatically disconnect the electrical circuit when the current flowing through the breaker exceeds the permissible value for a given system.

The Type C tripping characteristic means that the breaker reacts to medium-sized short-circuit currents and is intended for general applications in homes as well as small and medium-sized enterprises. This is the most common characteristic used in electrical installations.

The rated operating voltage is 400 V, which corresponds to European standards for three-phase networks. The rated current of this model is 25 A,
