INTRODUCE

FU-LV30 serial low voltage current transformer is low cost ac current instrument transformer, measuring AC current from 5A to 3000 Amps passing through the center conductor. This model CT has six diameter version (Φ30mm, φ35mm, φ45mm, φ42*10mm, φ50*12mm, φ50*103mm), suite for all kinds of customers application. Low voltage 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). 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.
