Split Core Current TransformersHEYI ELECTRICAL

SCT Series

SCT range of split core current transformers have 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 ineternal precision resistor across the secondary winding of the ct provides

a low safe voltage output.

Current measurement, monitoring and protection for electrical wiring and equipment.

Current and power measurement for electric motors, lighting, air compressor, heating and venti lation system, air-condition equipment and

automation-control system.

Current, power and energy monitoring device.

Relay protection device.

Applications

FeaturesSplit core design, 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

Wires plugs, Audio plugs, Power plugs and so on five kinds of plugs
