Current transformer with openable core 600-5A class 0.5 TO-600-5

Current transformer with openable core – precise measurement and protection

The TO-600-5 current transformer is a reliable device used for safe and accurate current measurement in electrical circuits. The design with an openable core allows installation without the need to interrupt the circuit, which significantly simplifies installation and maintenance. This is a key solution for both professional installers and end-users who value convenience and minimizing downtime.

### Characteristics and application

The TO-600-5 transformer is designed to work with measuring and protective devices, converting high current intensities (up to 600A) into values safe for these devices (5A). Thanks to the accuracy class of 0.5, it provides precise readings, which is important in applications requiring high measurement reliability. The use of a transformer with an openable core is particularly useful in existing installations where access to wires is limited. The device finds application in electrical switchboards, control cabinets and energy consumption monitoring systems.
