INTRODUCE

FU-30II economic low voltage current transformer is low cost ac ring type current transformer, measuring AC current from 15A to 300Amps passing through the center conductor. This model has three version (class 0.2, 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 TRANSFORMER. LV current transformers are supplied with accessories which help to install and secondary terminal cover with possibility of sealing. 
All of our GFUVE low voltage current transformers are strictly comply IEC60044-1, IEC61869-2, ANSI/IEEE C57.13, GB1208-2006, GB/T 20840.1-2010, GB/T 20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN 61010-2-031, IEC60185, JJG1021.
