Quick Details
Specifications
Feature:
1: Double-screw fastening, safe, easy to install, portable.
2: Wide inner window, allowing clamping of big cables or bus-bars.
3: Wide range of sizes to accommodate all the existing installations.
4: Primary current from 5A to 5000A.
Advantage:
1: All the cases are made of import USA dupont PA materials, not the ABS material case, So the temperature endurence is much higher;
2:All the cores are made of imported highest quality silicon iron sheet, So the core's magnetic
performance is much higher;
3:All the parameters are double cross-checked, so the testing results is much ensured! Small size and easy mounting
4:Wide inner window, allowing clamping of big cables or bus bars
5:Wide range of size
Applications:
1:Current measurement, monitoring and protection for electrical wiring and equipment.
2:Current and power measurement for electric motors, lighting, air compressor, heating
and ventilation system, air-condition equipment and automation - control system.
3:Current, power and energy monitoring device.
4:Relay protection device.
