VFC serial is a combination of AC High Voltage Vacuum Contactor and Fuse. It is applied in industrial control system with 50/60Hz frequency, 12kv rated voltage,225A(Max.) rated current. 
It can be matched with switchgear to built F-C circuit and used together with general protection. 
It can control and protect high voltage motor, transformer and capacitor bank.

“Eight Protection” is a reliable mechanical interlocking device. 
The following electrical fault operation can be prevented:
1.When the contactor is opened, the cart can be moved;
2.When the cart is in break/test position and operation position, the contactor can be closed;
3.When the earthing switch is in open position, the cart can be moved from test position to operation position;
4.When the cart is in any position between operation and test, the earthing switch can not be closed;
5.Only when the cart is in break/test position, the earthing switch can be closed;
6.Only when the cart is in break/test position, the door of the cart can be opened;
7.When the cart is in operation position, the quadric plug will be locked and can not be pulled out;
8.When the contactor is in close position, no matter the cart is in the operation or test position, the cart can not be moved.
