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