The product description

Split Core Current Transformers

GWSCCT681B Series

GWSCCT681B 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 energy monitoring device.

Relay protection device.
