Current transformer - three-phase, rated voltage 720V AC, 200/5A TP-200-5

Three-phase current transformer – precise measurements and installation protection

This three-phase current transformer is a reliable tool for indirect current measurements in electrical installations. The closed-core design ensures measurement accuracy and stability, and the 200/5A ratio allows for safe and effective load monitoring. The transformer is designed to work with control and measurement devices, enabling precise analysis of network parameters.

Construction and application

The TP-200-5 current transformer is designed for direct mounting on the outputs of power disconnectors, which significantly speeds up the installation process and saves space in the switchgear cabinet. The current-carrying conductor passes through the transformer opening, generating a signal on the secondary winding proportional to the current intensity in the primary circuit. This solution is used in energy consumption monitoring systems, overload protection, and applications requiring precise current measurement.
