Product Description

Product Description

General structure
ZW32-12 series vacuum circuit breaker is small size, sealed structure. It consists of poles, CT, spring or permanent magnet mechanism and enclosure. Spring mechanism is sealed in the enclosure. 


Operating mechanism: manual/ motor, spring mechanism / permanent magnet motor
Disconnecting switch: disconnecting at one side or both sides ( if needed)
Optional: CT, zero CT, PT, surge arrester
Control and protection: inrush current controller
Bell type FTU (optional)
Box type FTU (optional)
Installation: pole mounted 

features

1. Permanent magnet operation mechanism of excellent performance is available. It is a kind of operation mechanism which is actuated by electromagnet and maintained by permanent magnet. It is a monostable mechanism. Vacuum circuit breaker is open by contact spring and open spring. With few moving parts when working, it has very long mechanical life and high reliability.
2. Close and open can be operated by manual or motor, or remote control. It can be combined with recloser controller or section controller to form automatic recloser or automatic sectionalizer. 
3. Two-phase or three-phase CT can be added to protect overcurrent and short circuit. Metering CT can be added upon request.
