Split Core Current Transformers SCTK731 Series SCTK731 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.  Features  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  Applications  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.  Circuit connection diagram  Technique Index Electrical Parameter Mechanical Parameter Frequency 50-400Hz Case PC /UL94-V0 Rated Input 5A-5000A Bobbin PC Measuring range 5%In-130%In Core Silicon steel Rated Output 0-5A Internal structure Epoxy Ratio ≤ ± 0.5 ％ Construction Screw Phase angle ≤ ±30min Operating Temp －25℃～＋75℃ Dielectric strength 2.5KV/1mA/1min Operating Humidity
