China Current Transformers Manufacturer Low Voltage Current Transformers Manufacturer Mini Current T

Product Description
0.5-630A 0-500mA Split Core Power Current Transformer1. ApplicationSCTK661 serLaboratory Instruments ies retro-fit (split-coreEncoder ) 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. FeatureThe 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.3.
