Current transformer 40/5a 22, class 1 TI-40-5

Current transformer for precise measurements

This current transformer, with a transformation ratio of 40/5A, is indispensable in measurement and protection systems. It provides safe and accurate monitoring of current in electrical circuits. The closed-core design and accuracy class 1 guarantee reliable readings, which is crucial for both professional installers and end-users. The aperture diameter of 22 mm allows it to work with a wide range of conductors.

Construction features and application

The transformer is designed to operate in single-phase systems. Its construction based on the principle of a through-type current transformer allows current measurement without the need to interfere with the primary circuit. Using the transformer in industrial installations, public buildings, or energy monitoring systems allows for precise load control and protection against overloads. Made with attention to detail, with 4 mm² screw connections, it ensures stable and reliable connections.

Key advantages and parameters
