The product description

Split Core Current Transformers

GWSCCT660A Series

GWSCTC660A 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.



 The structure of the self-locking, safe, easy to install, portable

  Wide inner window, allowing clamping of big cables or bus-bars


Wide range of sizes to accommodate all the existing installations




§Current measurement, monitoring and protection for electrical wiring and equipment.


 Current and power measurement for electric motors, lighting, air compressor,


heating and ventilation system, air-condition equipment and automation – control

 system.Current, power and monitoring device.
