Protection of circuits against short-circuit currents, protection of circuits against overload currents, switch, isolation.
NB1-63H circuit-breakers are used in domestic installation, as well as in commercial and industrial electrical distribution systems.
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.
C curve (5-10In)
protection for circuits that supply loads with high inrush current at the circuit closing
(LV/LV transformers, breakdown lamps).
