SCTK667B Series Double Screw Split Core Power Low Safe Voltage Current Transformers with 5 to 3000A input
SCTK667B Series split core CTs Double screw 5A-3000A split core power low safe voltage current transformers
Product Description
1) Application
SCTK667B 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.
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.
2) Feature
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
