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.
Current transformers such as the Carlo Gavazzi CTD2X505AXXX allow AC current to be monitored conveniently by converting the current flowing through the primary conductor into a proportional lower secondary current. The resulting 5 A signal can be connected to compatible energy meters, multifunction meters, power analysers and electrical monitoring equipment.
The CTD-2X series is designed for electrical distribution and industrial monitoring systems where dependable current transformation and practical installation are required. Its solid-core construction, standard 5 A secondary output, stepped conductor aperture and integrated DIN rail mounting make the CTD2X505AXXX particularly suitable for new switchboards, control panels and monitoring systems requiring a 50 A primary current rating.
