Sctk731 Split Core Type Current Transformer with UL Approval

STCK731 series retro-fit (split-core) current transformer has been specially designed to facilitate theri installation in new or already existing net works. They may be installed without opening any cable or bus-bar circuit. An internal presision 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-bar
Wide range of sizea to accommodate all the existing installationsApplications
Current measurement, monitoring and protection for electrical wiring andequipment. Current and power measurement forelectric motore, lighting, air compressor, heating and ventilation system, air-condition equipment and automation-control system.
