INTRODUCE
FU-50II low voltage high accuracy current transformer is economic ac window type current transformer, measuring AC current from 200A to 800Amps passing through the center conductor. This model has five version (class 0.2s, 0.2, ,0.5s, 0.5, 1), suite for all kinds of electrical customers application. LV current transformers are intended for supplying measuring instruments and protection circuits of electrical power devices with a maximum operating voltage of 0.72kV and frequency of 50Hz or 60Hz after prior arrangement with the manufacturer of GFUVE GROUP. LV current transformers are supplied with accessories which help to install and secondary terminal cover with possibility of sealing.
