P 009 Low Voltage Brief Catalogue -
NB8-63M
1. General
1.1 Function protection of circuits against short-circuit currents, switch, isolation. NB8 -63M 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: C curve (6.4In-9.6In) protection for resistive and inductive loads with low inrush current. D curve(9.6-14.4In) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps). 1.3 Certificate CE
