Chint miniature circuit breaker NB1-63-2P 16A UL certificated

Chint miniature circuit breaker NB1-63-2P 16A UL certificated
Product Detailed
Electric ratings: a. AC: up to 63A, AC230/400V, AC50/60Hz; b. DC: up to 63A, DC110V/1P, DC125V/2P

Application: for protection of circuits from over-load and short-circuit; and for infrequent making and breaking of circuits under normal operation conditions, as well; Standard: IEC/EN 60898

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 electrical distribution systems.

Selection:technical data of the network at the point considered: the earthing systems(TNS,TNC),

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(3-5ln)

protection for people and big length cables i TN and ITsystems.

C curve(5-10ln)

protection for resistive and inductive loads with low inrush current.

D curve(10-14ln)

protection for circuits which supply loads with high inrush current at the circuit closing(lv/lv transformers,breakdown lamps).
