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.
