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.
Features
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
Applications
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.
