Outline Dimension drawing：
Zhikai ,we own production and sales of own brand, technical support,OEM, ODM and so on.
Specification:
Low voltage split current transformer inner hole size is 45mm.
Split core current sensor, similar items, 10mm up to 50mm
Precise current transformer,class 0.5, class 1
Note: The current Ratio above are common type, other specifications can be provided according to customers’ requirements.
The CT primary should be connected in series with the test current loop, the secondary should be as work in the short-circuit state
The secondary circuit is not allowed open circuit, if open , has the high voltage ,so please do not install fuse.
Application:
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.
Package:
Inner box(3pieces), outer carton
