Description of Model
       
       Vacuum load break switches (LBS for short) are only requested to switch load current, or say to break rated working current. LBS often assume to be integrated together with fuse as short circuit protection units. LBS  is qualified to do frequent operations under a very hostile environment because of its features in strong arc extinguishing ability, long life cycle, minimiezed maintenance, reliable performance, safety, compact and light weight. Vacuum interrupters, however, as the most important part determine its performance in a certain degree.

       Main technical data is: rated voltage ranging from 7.2KV to40.5KV; rated current ranging from 630A to 1250A; rated short time withstand current ranging from 12.5KA to 25KA. Our vacuum interrupters are designed to operate under GB/T3804-200 or E1 level of IEC60265-1 standards.
