1 Pole 20A MCB C curve 4.5kA NB163 186419

1 Pole 20A MCB C curve 4.5kA NB163 186419

DESCRIPTION -

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.

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 resistive and inductive loads with low inrushcurrent.
