DETAILS

Description:
FZW33 12KV/24KV Outdoor AC vacuum disconnect load breaker is a new product adopts domestic existing mature load breaker switch production experience and overseas advanced technology to design and manufacture. The load breaker is composed of disconnect blade, vacuum interrupter and operation mechanism. vacuum extinguishing arc, there are merits as strong extinguishing arc ability, reliable performance, long lifetime, small volume, no explosive danger and no pollution to environment.
It accords with the standards of IEC62271-102 & GB/T3804:3.6~40.5kV High voltage switches, IEC60694 & GB/T11022: High voltage switch apparatus and control apparatus.
