 HY122-30M-LE split core current transformer

HY122-30M-LE split core current transformer

The KCT range of split core current transformers have been specifically designed to be small CT and easy to open and yet

 maintain the accuracy required for kwh meters. The benefit of a split core current transformer is that it can be placed

 into position easily and without disturbing or disconnecting the main cables it is monitoring.


1:The structure of the self-locking, 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:Isolated plastic case recognized according to UL94-V0
5:Wires plugs,Audio plugs,Power plugs and so on five kinds of plugs


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.
