CY-KCT01A (75-600A) Split Core Current Transformers

The”KCT01A Split Core Current Transformers” are designed for easy installed without the need for dismantling the primary busbar or cables. They output 5A or 1A standard secondary currents which can directly match the input terminals of electric energy meter and measure and control instruments in power system. They are applied to electric measure and control equipments like power electric energy meter, switch cabinet , control cabinet, etc.

Features:

.Small size , light weights and exquisite appearance .Easily install, no need to disconnect  primary busbar.With over-voltage protection in open circuit

Applications:

.Electric  energy  meter .Switch cabinet .Smart grid .Power measurement and system
