General structure
ZW32-12 series vacuum circuit breaker + recloser is small size, sealed structure. It consists of poles, CT, spring or permanent magnet mechanism and enclosure. Spring mechanism is sealed in the enclosure.
It has multi-protection and functions, such as overload, short circuit, quick break, earthing, reclosing, remote control and remote communication.
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
- 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.
- 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.
- Two-phase or three-phase CT can be added to protect overcurrent and short circuit. Metering CT can be added upon request.
