12kV SIRING Integrated Vacuum Circuit Breaker

Product Introduction
SIRING® series solid insulation switch modules, together with reliable, universal and modular breaker spring operating mechanism and three-station operating mechanism, constitute SIRING® series solid insulation switch units. The operating mechanism, which has passed the type test, is a mature and reliable product with many years of operation experience, and all its technical parameters meet the code requirements and the standards of electric power industry and power grids.
 
●Reliable circuit breaker + three-station operating mechanism: the circuit breaker mechanism has passed 10000 times test and the three- station mechanism has passed 5000 times life test.
 
●The solid insulation module and the mechanism are factory-pre-assembled, and hoisted into the cabinet as a whole, facilitating assembly and maintenance.
 
●The circuit breaker mechanism can be manually + electrically operated, and the three-station mechanism can be manually + electrically operated, facilitating the automation of power grid.
