Product Description

LZCK310-10 100/5A Cast Resin Split Core Current Transformer


LZCK310-10 Cast Resin Split Core Current Transformer 100/5 applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV, and microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, have the characteristics of Small magnetic circuit loss and can be cut, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case which is flame retardance anti-moisture, stable performance, no maintenance.
