NB1-63G Miniature Circuit Breaker

1.1 Function

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.
 

1.2 Selection

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.
 

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 inrus current.
