## Summary description

FF TI-80-5 is a current transformer with a primary/secondary ratio of 80/5 A, 22 mm window diameter and accuracy class 0.5. Designed for measurement and protection circuits, it provides precise current scaling for meters, relays and monitoring equipment. Suitable for panel or enclosure mounting where a compact CT with defined accuracy is required.

## Long description

FF TI-80-5 is a window-type current transformer with a primary/secondary ratio of 80/5 A and a 22 mm window diameter, accuracy class 0.5. It is intended for measuring and protection circuits and provides stable, linear current scaling for meters, protection relays and monitoring equipment. The compact design allows panel or enclosure mounting in applications where a defined accuracy and a small footprint are required.
Advantages
The transformer offers a precise 80/5 A conversion with class 0.5 accuracy, ensuring reliable readings for measurement and protection devices. Its 22 mm window diameter supports easy through-wiring of conductors while minimizing space usage. Robust construction and standardized performance characteristics make integration straightforward in electrical panels and switchgear.
Suitable for
Current measurement for energy meters and monitoring systems
Input for protection relays and trip circuits
Panel or enclosure installations with limited space
Retrofit projects requiring a compact, defined-accuracy CT
Key specifications
Primary/secondary ratio: 80/5 A
Window (aperture) diameter: 22 mm
Accuracy class: 0.5
Type: window (through-core) current transformer
Intended application: measuring and protection circuits
How to use
Install the transformer so that the conductor carrying the primary current passes once through the 22 mm window. Secure the device according to panel or enclosure mounting guidelines and connect the secondary terminals to the meter or protection relay using appropriate gauge wiring. Ensure the secondary circuit is never open-circuited under load and, where required, apply a suitable burden (load) within the transformer's rated limits to maintain accuracy class 0.5.
Usage recommendations
Verify conductor size and orientation before installation, maintain the specified burden on the secondary, and follow local wiring and safety standards. For protection applications, confirm compatibility with the connected relay's input requirements and perform functional checks after installation.
