LMCK185-10 IP65 waterproof split core outdoor Current Transformer

Whole view of the 185mm diameter ABS and PC Cover outdoor Current Transformer

LMCK series outdoor 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&PC) which is flame retardance anti-moisture, stable performance, no maintenance.
