Introduce
DP range of split core current transformers have been designed to easily fit around cables without breaking the circuit.Its advantages of big capacity and big
mounting hole size,could be used in more power applications.DP was global used in most power applications.
Applications
Current measurement, monitoring and piotection 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.
Features
Double-screw fastening, safe, easy to install, portable.
Two built in fixing methods:Base;Busbar mounting
Wide inner window, allowing clamping of big cables or bus-bars.
Wide range of sizes to accommodate all the existing installations.
Primary current from 5A to 5000A.
