FZW32-40.5outdoor AC high voltage vacuum load-breaking switch is a new type of load switch designed manufactured via integrating the mature experience of domestic existing load switch production and foreign advanced technology.
- Structure: ACB
- Poles Number: 3
- Certification: ISO9001-2000
- Operation: Energy-storage Type
- Installation: Fixed
- Arc-extinguishing Medium: Vacuum
The mechanism of FZW32-40.5is designed as a whole with vacuum interrupter. Specialized 3AF type spring operating structure from Siemens can be operated by manual or carry out direct current energy saving operation. It's can be designed as 350mm, 400mm, 460mm and other kinds of phase space, which matches better with different kinds of switchgear, such as fixed type XGN17-40.5, type JYN1-40.5, KYN10-40.5.
