## Long description

The FF TI-250-5-02S is a high-precision current transformer engineered for reliable electrical measurement and monitoring. Designed to convert high primary currents into manageable secondary signals, this device is essential for accurate energy metering in industrial and commercial electrical distribution systems. Its robust construction ensures consistent performance and signal integrity, making it a dependable component for secondary measuring instruments and energy management systems.
Advantages
This current transformer stands out due to its high accuracy class of 0.2S, which ensures precise data collection even at low current levels. The device is built to maintain stability under varying load conditions, providing consistent output for connected meters and protection relays. Its compact design allows for efficient installation in standard electrical panels, while the durable materials used in its manufacturing guarantee a long service life and resistance to environmental stressors common in industrial settings.
Suitable for
Industrial energy monitoring systems
Commercial electricity billing and sub-metering
Integration with secondary measuring instruments
Electrical distribution panel monitoring
This device may not be suitable for applications requiring high-voltage insulation beyond its specified ratings or for environments with extreme electromagnetic interference that could compromise signal accuracy. It is also not intended for use in circuits where the primary current consistently exceeds the rated transformation ratio.
Key specifications
Transformation ratio: 250/5A
Accuracy class: 0.2S
Primary current: 250A
Secondary current: 5A
How to use
The installation of the FF TI-250-5-02S should be performed by a qualified electrician in accordance with local electrical codes. The primary conductor must be passed through the aperture of the transformer, ensuring proper orientation as indicated by the device markings. The secondary terminals should be connected to the measuring instrument using appropriately sized wiring to minimize resistance. Always ensure that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage buildup.
What to consider before purchase
Verify that the transformation ratio matches your specific load requirements
Ensure the accuracy class meets the standards required for your metering application
Check the physical dimensions to ensure compatibility with your existing panel space
Confirm that the secondary current output is compatible with your measuring devices
Usage recommendations
Regularly inspect the terminal connections for tightness and signs of oxidation to maintain optimal signal transmission. Ensure that the transformer is kept clean and free from dust or moisture accumulation to prevent potential insulation degradation over time.
