The product description
Split Core Current Transformers
GWSCCT667A-040 Series
GWSCCT667A-040 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
Double-screw fastening, 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.
