Why Choose the Carlo Gavazzi CTD2X2005AXXX Current Transformer?
The Carlo Gavazzi CTD2X2005AXXX is a compact and accurate solid-core current transformer (CT) designed for AC current measurement in industrial electrical installations, energy monitoring systems and power distribution equipment. As part of the Carlo Gavazzi CTD-2X series, it provides dependable current transformation for use with compatible energy meters, power analysers and electrical monitoring equipment.
This current transformer converts the current flowing through a primary cable or busbar into a proportional secondary current that can be safely measured by compatible instrumentation. Its solid-core through-feed construction provides a robust solution for permanent installations, while the stepped opening accommodates both cables and common industrial busbars. Integrated DIN rail mounting, panel mounting facilities and screw-terminal connections help simplify installation within electrical panels and switchboards.
With a rated primary current of 200 A and a 5 A secondary output, the CTD2X2005AXXX provides a transformation ratio of 200/5 A. It features Class 0.5 accuracy, a 4 VA rated secondary apparent power, a 24 mm cable aperture and support for busbars up to 32 mm wide, making it well suited to accurate industrial current measurement and energy monitoring applications.
