MCB Icn=10000A / Icu=15kA 4P C 25A NCN425

The overcurrent breaker marked as Icn=10000A / Icu=15kA 4P 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 protect cables and lines from damage resulting from excessive current flowing through the circuit. This breaker is characterized by its ability to withstand short-term surges up to a value of Icn equal to 10000 amperes, which demonstrates its high resistance to sudden increases in current intensity.

On the other hand, the Icu parameter, which defines the maximum breaking capacity, is as high as 15000 amperes, ensuring safety even in the case of very large overloads or serious network failures. The Type C tripping characteristic informs us that the breaker reacts quickly to
