Protection of circuits against short-circuit currents,protection of circuits against overload currents,switch,isolation.
1. General
1.1 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 ofthis 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.
