630A/0.5A Split Core Current Sensor , Customizable Relay Protection Device
The 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. Apply to 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.
