The Carlo Gavazzi CTD10V12505AXXX is a high-performance solid-core current transformer (CT) designed for accurate AC current measurement in industrial energy monitoring, metering and power management applications. As part of the Carlo Gavazzi CTD10V series, it provides a reliable measurement interface between high-current electrical circuits and compatible energy meters, power analysers, transducers and monitoring equipment.
With a rated primary current of 1250 A and a standard 5 A secondary output, the CTD10V12505AXXX provides a 1250/5 A transformation ratio for high-current AC measurement. The transformer supports Class 0.5 accuracy at 15 VA, with higher available burdens of 25 VA at Class 1 and 30 VA at Class 3, providing flexibility for a range of industrial metering applications.
The CTD10V12505AXXX features a solid-core construction intended for permanent installation around conductors or vertical busbars. It has a 51 mm opening diameter and accommodates busbars up to approximately 50 × 125 mm, making it well suited to switchboards, distribution panels and high-current industrial electrical systems.
Current transformers such as the Carlo Gavazzi CTD10V12505AXXX reduce high primary currents to a proportional secondary current that compatible measuring instruments can monitor. Its 1250/5 A ratio allows a 1250 A primary circuit to be represented by a standard 5 A secondary signal for energy meters, power analysers, transducers and other electrical measurement equipment.
The solid-core construction is particularly suitable for permanent installations where measurement accuracy and long-term reliability are important. With Class 0.5 accuracy at 15 VA and accommodation for large vertical busbars, the CTD10V12505AXXX is well suited to industrial switchboards and distribution systems requiring dependable monitoring of high-current feeders.
