Application:

1.NOB7 belong to the advanced level of the nineties in the world instead of the older generation of L7.

 

2.They have protective function as shortage as overload, and are used in lighting distribution system in industry, commerce and dwelling, and protect fractional electric motors.

 

3.They have many merits of high protective grade(up  to  IP20),high  breaking  capacity, reliable sensitive action, convenient, multi pole assembling. long life etc. They are mainly adapted to the circuit of AC 50Hz, 230V in single pole, 400V in double, three, four poles for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.
