Circuit breaker Icn=10000A / Icu=15kA 2P C 4A NCN204

The miniature circuit breaker marked as Icn=10000A / Icu=15kA 2P C 4A 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 quickly disconnect the electrical circuit in the event that a current exceeding the permissible value for a given system is detected.

The Type C tripping characteristic means that this breaker has a moderate time delay when operating on short-term overloads and reacts quickly to the occurrence of large short-circuit currents. This is a particularly desirable feature in circuits with electric motors or other inductive devices, where transient current increases may occur during startup.

The rated switching capacity of Icn=10000 amperes informs us about the
