NB8-63
General
1.1 Function : protection of circuits against short-circuit currents, protection of circuits against overload currents, switch,
isolation. NB8 -63 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 considered: 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(10-16In) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
1.3 Certificate : CE
