SCTK661 Series AC 0.333V Split Core CT 0-500mA Current Transformers,wide inner window,Customizable
SCTK661 series retro-fit (split-core) current transformer has been specially designed to facilitate their installation in new or already existing net works.They may be installed without opening any cable or bus-bar circuit. An internal precision resistor across the secondary winding of the CT provides a low safe voltage output.
