China [CN] 
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. The KCT range of current transformers has two insulated terminal covers for connecting the S1 and S2 cables which lock down over the terminal screws fully insulating the connections. This makes it ideal to use Autometers cable hamesses which are colour coded and individually numbered on each conductor ensuring simple and easy connection from the current transformer to the electricity meter.
Features:
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
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.
