Current transformer 1000/5A, class 0.5 TI-1000-5

Current transformer – precise measurement, reliable protection

Current transformer TO-1000-5 is a key element in measurement and protection systems, designed to safely and accurately transform large currents into smaller values acceptable by standard meters and relays. The device finds application in both industrial installations and commercial and residential buildings where precise load control and protection against short circuits are required.

Construction and application

The TO-1000-5 transformer is a through-type model, meaning the conductor with the measured current flows directly through its opening. This design minimizes the impact on the primary circuit and ensures high measurement accuracy. Accuracy class 0.5 guarantees reliable results even under high loads. The transformer is particularly useful in applications where it is necessary to monitor large currents without directly connecting measuring devices to the high-voltage circuit. This makes it possible to safely and effectively monitor energy consumption, detect overloads and implement protection functions.

Key features and benefits

• High accuracy: Accuracy class 0.5 ensures precise current measurements, which is crucial for the proper operation of monitoring and protection systems.
• Large measurement range: Rated primary current of 1000 A allows the transformer to be used in installations with high loads.
• Safety: Galvanic isolation between the primary and secondary circuits ensures the safety of operators and protects measuring devices from damage. The insulation withstand voltage is 3 kV/1 min.
• Solid construction: Made of high-quality materials, guaranteeing the durability and reliability of the device even in harsh working conditions.
• Easy installation: The transformer has a secondary circuit connection using a screw connection, which facilitates its installation and integration with existing systems.
• Compliance with standards: Meets the requirements of IEC 60044-1 standard, confirming its quality and safety of use.
• FS 5 overload factor: Allows for short-term exceeding of the rated current without damaging the device – important when starting motors or other devices with high starting current.
• Touch protection: Provides additional safety during device operation.

The TO-1000-5 transformer is a reliable tool for professionals involved in electrical installations and for end-users who care about the safety and energy efficiency of their facilities. Its precision, durability and ease of installation make it an ideal choice for a wide range of applications.
