BEIJING GFUVE ELETRONICS CO.,LTD.

LMCK series outdoor waterproof current transformers are applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV also can be used for microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, has the characteristics of Small magnetic circuit loss and can be split, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case(ABS or PC) which is flame retardance anti-moisture, stable performance, no maintenance. ----------------------------------------------------------------------------------------------------------------------- FEATURES: 1.Waterproof 2.PC or ABS Cover 3.Split Core 4.50mm Diameter 5.Silicon Steel 6.0.5% 1% 7.100-1500A --------------------------------------------------------------------------------------------------------------------- PARAMETERS Technical parameters　 Standards IEC60044-1; IEC 61869-2; NTC 2205; GB1208-2006 Accuracy Class 0.5%, 1% Range of primary rated current 100-1500A Range of Rated load ≤10VA Rated frequency 50/60Hz Rated secondary current 5A or 1A Secondary winding power frequency withstand voltage 3kV, 1min Safety Factor Rating (FS) <5 Flame retardant ABS plastic shell inside, jaw waterproof apron.
