Why Choose the Carlo Gavazzi CTD2X1255AXXX Current Transformer?
The Carlo Gavazzi CTD2X1255AXXX 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 construction provides a robust solution for permanent installations, while the stepped aperture accommodates cables and common industrial busbar sizes. Screw-terminal connections and flexible mounting options simplify integration into electrical panels and switchboards.
With a rated primary current of 125 A and a 5 A secondary output, the CTD2X1255AXXX provides a transformation ratio of 125/5 A. It features Class 0.5 accuracy, 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.
