NB1-63 Miniature Circuit Breaker

1.1 Function

protection of circuits against short-circuit currents,protection of circuits against overload currents,switch,isolation.

NB1 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 curve:

C curve (5-10In)

protection for resistive and inductive loads with low inrushcurrent.
