Current transformer - three-phase, rated voltage 720V AC, 300/5A TP-300-5

Three-phase current transformer 300/5A – precise measurements in your installation

This three-phase current transformer from F&F is a reliable tool for indirect current measurements in three-phase networks. Designed for a wide range of applications, from energy consumption monitoring systems to advanced industrial installations, it provides accurate and stable readings. The closed-core design guarantees high precision, and the accuracy class 1 confirms its reliability.

Construction and application

The TP-300-5 current transformer is characterized by a 300/5A ratio, which means that a primary current of 300A is converted into a secondary current of 5A. This allows for safe and efficient measurements using standard meters and control-measurement devices. Thanks to its compact dimensions (76.5 x 74 x 80 mm) and the possibility of mounting on a DIN rail, panel or cable, the transformer easily integrates with existing infrastructure. Application in electrical switchboards allows for monitoring load and optimizing energy consumption.

Key features and benefits
