Current transformer for precise measurements and protection

This open-core current transformer with a transformation ratio of 1000/5 A is a reliable tool for measuring current and providing protection in electrical installations. Its design allows for easy installation and removal, which is particularly useful during servicing or modernization of installations. This transformer finds application both in measurement systems and in circuits protecting against overloads and short circuits.

Construction and application

The current transformer converts a high primary current (up to 1000 A) into a lower, safe secondary current (5 A), which can be measured by standard meters and relays. The open-core design facilitates its installation on energized conductors without the need to interrupt the circuit. This makes it possible to take measurements or install the transformer even in operating installations. Accuracy class 0.5 guarantees precise measurements, which is crucial in applications requiring high accuracy readings.

Key features and benefits

• Touch protection: Ensures user safety by minimizing the risk of accidental contact with energized components.
• High accuracy: Accuracy class 0.5 ensures precise current measurements, which is important for the correct operation of measurement and protection systems.
• Easy installation: The open-core design facilitates installation on conductors without the need to interrupt the circuit – saving time and costs during service or modernization.
• Rated apparent power 5 VA: Suitable for cooperation with a wide range of meters and relays.
• Calibration: The transformer is calibrated, which confirms its compliance with applicable standards and enables its use in billing applications.
• Screw connection of the secondary circuit: Provides a secure and durable connection of the secondary conductors.
• Power consumption 5 W: Low power consumption of the transformer minimizes energy losses in the installation.

This transformer is an ideal solution for both professional installers and end-users looking for a reliable tool for measuring current and protecting electrical installations. Its solid construction and high quality of workmanship guarantee long-term and trouble-free operation.
