General
DFY1,2type Energy metering Joint junction box is the special junction box of energy metering device standard connection, also apply to the secondary circuit of rated voltage to 660V,rated current to 20A, As the use of electric instrument under Load condition to Security exchange or On-site inspect electric energy meter ,electric instrument ,relay protection, to make sure of personal operation safety, enhance on-site working efficiency.
The technical index all meet national standard, Trial units reflect that after adapting new products , it effectively protect electric energy from Leaking into account and it is a good helper of energy metering, which plays an active role in preventing the occurrence of energy measurement.
