Knife Switch Disconnector is suitable for AC 50Hz, rated voltage 380V, AC voltage 380V, DC to 440V, rated current to 1500A, as a complete set of distribution devices, which can be used to switch on and off AC and DC circuits manually or as disconnectors infrequently.

 

Among them:

1. The single-switch and double-switch with central handle are mainly used in substations. They do not cut off the circuit with current and serve as isolation switches.

2. Side-operated handle-type knife switch is mainly used in power box.

3. The cutter switch of the central front lever operating mechanism is mainly used in the switch cabinet for front operation and rear maintenance. The operating mechanism is installed in front of the switch cabinet.

4. Side front-operated mechanical knife switch is mainly used in front-operated and front-maintained switchgear. Operating mechanism can be installed on both sides of the cabinet.
