SCTK667A Series Split Core 100 to 1000A input CT, Current Transformers,Current sensor
SCTK667A 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. It can save time and the installation costs. Mainly used in
