CTD2X1501AXXX – CURRENT TRANSFORMER REV.25

Why Choose the Carlo Gavazzi CTD2X1501AXXX Current Transformer?

The Carlo Gavazzi CTD2X1501AXXX 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 both cables and common industrial busbar sizes. A double set of connection terminals and integrated DIN rail mounting facility help simplify installation within electrical panels and switchboards.

With a rated primary current of 150 A and a 1 A secondary output, the CTD2X1501AXXX provides a transformation ratio of 150/1 A. It features Class 0.5 accuracy, a 24 mm cable aperture and support for busbars up to approximately 32 mm wide, making it well suited to accurate industrial current measurement and energy monitoring applications.
