FU-40II200A-500A LOW COST RING TYPE LV CURRENT TRANSFORMER

FU-40II economic low voltage current transformer is low cost ac ring type current transformer, measuring AC current from 100A to 800 Amps 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 0.72 kV and frequency of 50 Hz or 60 Hz 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. All of our current transformers are strictly comply IEC60044-1, IEC 61869-2, ANSI/IEEE C57.13, IEC 60185, NTC 2205, GB1208-2006, GB20840.1, GB20840.2, JJG1021.
