When it may not be suitable

This transformer is not intended for use in high-voltage transmission lines or environments exceeding its specified insulation and thermal ratings. It is also not suitable for applications requiring a different transformation ratio or a higher accuracy class than 0.5.

Key specifications

• Transformation ratio: 1250/5 A
• Accuracy class: 0.5
• Application: Current measurement and monitoring

How to use

The FF TI-1250 should be installed 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. The secondary terminals must be connected to the measuring device using appropriately sized wiring. Ensure all connections are secure and that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage spikes.

What to consider before purchase

• Verify that the 1250/5 A ratio matches your specific load requirements.
• Ensure the physical dimensions fit within your existing electrical enclosure.
• Confirm that the 0.5 accuracy class meets the standards required for your monitoring or billing application.

Usage recommendations

Always ensure the secondary terminals are connected to a load or short-circuited before energizing the primary circuit to prevent damage to the transformer and ensure operator safety.
