protection of circuits against short-circuit currentsprotection of circuits against overload currents,switch,isolation,
NB1-63G circuit-breakers are used in domestic installation,as well as in commercial and industry electrical distribution systems.
Technical data of the network at the point consideredshort-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device,
Network normal voltage.
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 inrus current.
