ZFCC5-7.2(12) Combination of High Voltage Vacuum Contactor & Fuse
ZFCC5 serial is a combination of AC High Voltage Vacuum Contactor and Fuse. It features for the industrial control system that frequency: 50Hz, rated voltage: 12kV(7.2kV), rated current: 225A Max. (for 7.2kV: 315A Max.). It can be matched with switchgear to built F-C circuit, be used together with general protection. It can control and protect high voltage motor, transformer and capacitor bank.
Products design:
1. ZFCC5 is a F-C combination of JCZ5 Vacuum Contactor and High Voltage Current Limiting Fuse by series. The control function is realized by JCZ5 Vacuum Contactor and the protection function is realized by High Voltage Current Limiting Fuse.
2. ZFCC5 use VSI (ZN63A) breaker base cart as the swing bar structure. It has the compact structure, and its dimension is matched with KYN28 high voltage gear.
Five Protection use the reliable lock structure, can be avoided the below mentioned electrical wrong operation:
1. When the contactor is opened, the cart can be moved.
2. When the cart is in operation position or break test position, the contactor can be closed.
3. The contactor is in the close position, whenever the cart is in the operation or test position, the cart can not be moved.
