Current transformer with openable core 1000-5A class 0.5 TO-1000-5

Current transformer with openable core – precise measurement, easy installation

This current transformer with an openable core is a reliable solution for measuring current in electrical installations. Designed to work with measuring and control devices, it enables safe and accurate monitoring of the load. The design with an opening core facilitates installation and removal without the need to disconnect wires, which is particularly useful during maintenance or modernization of installations.

Characteristics and application

The TO-1000-5 current transformer is characterized by a transformation ratio of 1000/5A and an accuracy class of 0.5, which guarantees high measurement accuracy. It is a single-phase device, ideal for use in energy consumption monitoring systems, overload protection, and applications requiring precise current measurement. Thanks to the possibility of opening the core, the transformer can be easily installed on existing wires without the need to interrupt them. Use in industry, energy and construction ensures the versatility of this component.
