Blend Switch (QFK5F)

QFK5F-45-0.4(0.23)series switching capacitor blend switch suit for controlling the switch-off of capacitor which is used in the low voltage three-phase all-compensate or single-phase separate-compensate reactive power auto-compensation system. It抯 made up by silicon controlled rectifier and contactor parallel connection .When switch-on ,it has the peculiarity of silicon controlled rectifier over-0 switching transcient,when closed path to normal run,it has the peculiarity of contactor's attaction.It has no flashy current to capacitor,extends the use life of capacitor and has the over current protection,over voltage protection,phase failure protection,has the function of display the voltage,current,capacity of capacitor and so on.
