Types of 0.5-630A Split Core Current Transformers with Epoxy Encapsulated Housing SCTK660A current sensor
Application
Current measurement, monitoring and protection for electrical wiring and Equipment.Current and power measurement for electric mo tors, lighting, Air compressor, heating and ventilation system, air-condition equipment And automation control system.Current ,power and energymonitoring device.
Feature
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.
Sctk660a series retro-fit (split-core) currenttransformer hasbeen specially Designed to facilitate their installation in new or already existing net works. They may beinstalled without openingany cableor bus-barcircuit.Aninternal Precision resistor across the secondary winding of the ct provides a low Safe voltage output.It can save time and the installation costs.
