1.1 Application

      Mainly used in the distributing and motor circuit which has high short-circuit current,and acted as main switch or master switch 

      infrequently operated by hand, it is particularly suitable in the relative high class with drawable low voltage complete equipment. 

      They provide safety isolation and protection against overcurrent for any low voltage electrical circuit.

1.2 Standard: IEC/EN 60947-3.

1.3 General characteristic 

      Full-enclosed structure

      Unique rolling insert type contact system.
