Why Choose the Carlo Gavazzi CTD2X505AXXX CTD-2X Current Transformer?
The Carlo Gavazzi CTD2X505AXXX is a compact solid-core current transformer (CT) designed for AC current measurement in electrical distribution, energy monitoring and industrial control applications. As part of the Carlo Gavazzi CTD-2X current transformer series, it converts the current flowing through a primary conductor into a standard secondary current suitable for compatible meters, power analysers and monitoring equipment.
This current transformer features a 50 A primary current rating and 5 A secondary output, providing a 50/5 A transformation ratio. Its accuracy class 3 and 1.5 VA rated secondary output make it a practical solution for general electrical current monitoring applications where a standard 5 A secondary signal is required.
The CTD2X505AXXX has a 24 mm cable aperture and supports busbar installations up to approximately 32 mm wide. Its stepped aperture accommodates common busbar formats including 30 × 10 mm and 25 × 20 mm, while screw-terminal connections and an integrated DIN rail mounting facility help simplify installation inside electrical switchboards, distribution panels and industrial control cabinets.
