Current transformer with openable core 750-5A class 0.5 TO-750-5

Current transformer with openable core – precise measurement and safety

This current transformer with an openable core is a reliable solution for measuring current in electrical installations. The design with an openable core allows installation without interrupting the circuit, which is particularly useful during the modernization of existing installations. Designed to work with circuits with a nominal current of 750A, it transmits a secondary signal of 5A, ensuring compatibility with a wide range of meters and monitoring systems. Accuracy class 0.5 guarantees precise measurements, essential in applications requiring high data reliability.

Characteristics and application

This transformer is used in measurement systems, energy consumption monitoring and electrical protection. Thanks to the possibility of opening the core, it is ideal for situations where access to the conductor is limited or when measurements need to be taken without disconnecting the power. Application in vertical or horizontal installations provides installation flexibility. The transformer complies with IEC 60044-1, which confirms its quality and safety. Made of high-quality materials, it ensures long-lasting and trouble-free operation even in harsh environmental conditions.
