    FUNCTION


    Protection of circuits against short-circuit currents,protection of circuits against overload currents,switch, isolation.


    SELECTION


    Technical data of the network at the point considered:the earthing systems (TNS,TNC),

    short-circuit current at the circuit-breaker installation point,which must always be less than the breaking capacity of this device,

    Network normal voltage.

    Tripping curves:

    B curve (3-5In)

    protection for people and big length cables in TN and IT systems.

    C curve(5-10In)

    protection for resistive and inductive loads with low inrush current.

    D curve(10-14In)

    protection for circuits which supply loads with high inrush current at the circuit closing

    (LV/LV transformers, breakdown lamps).
