Overview: Model QFJ6 power metering joint junction box is a special junction box for standard wiring of power metering devices. It is also suitable for secondary circuits with rated voltage up to 660V and rated current up to 20A. Used on site for safely replacing or inspecting electricity meters, electrical instruments, relay protection and other electrical equipment under load, ensures personal operation safety and improves work efficiency. Features: Used for testing electric equipment such as electricity meter, electric instrument and relay protection under load, ensuring personal operation safety and improving work efficiency. High impact strength, not easy to break, anti - moisture, good insulation performance. Anti-aging, flame retardant, high temperature resistant, it can work for a long time in in 40 ℃ to + 120 ℃. The connecting screws adopt compound groove combination technology, one word cross two kinds of screwdrivers are universal. The cover plate of the junction box is fixed with two screws, which is beneficial to prevent electric theft. The voltage circuit adopts one in and three out, and the voltage and current of each phase have phase sequence mark, which is convenient for joint connection and can avoid metering error caused by wrong phase sequence connection. A good helper of electric energy metering device.
