## Summary description

The FF TI-400/5 is a precision current transformer designed for accurate electrical measurement applications. With a power rating of 10VA and accuracy class 0.5, this device is engineered to step down high primary currents to a manageable secondary level for metering and protection equipment. It ensures reliable performance in industrial and commercial electrical distribution systems.

## Long description

The FF TI-400/5 is a precision current transformer engineered for accurate electrical measurement and monitoring. Designed to step down a primary current of 400A to a secondary output of 5A, this device provides a reliable signal for metering and protection equipment. With a power rating of 10VA and an accuracy class of 0.5, it ensures consistent performance in demanding industrial and commercial electrical distribution environments.
Advantages
This current transformer offers high measurement precision, which is essential for accurate energy billing and system monitoring. Its robust construction ensures long-term stability and reliability under standard operating conditions. By converting high currents into safe, measurable levels, it protects sensitive downstream equipment while maintaining high signal integrity for connected measuring devices.
Suitable for
Energy metering systems
Industrial power distribution panels
Electrical protection relays
Commercial building energy management
When it may not be suitable
This device is not intended for use in high-voltage transmission networks or environments where the primary current significantly exceeds the rated 400A capacity. It is also not suitable for applications requiring higher accuracy classes than 0.5 or for outdoor installations without appropriate protective enclosures.
Key specifications
Primary current: 400A
Secondary current: 5A
Power rating: 10VA
Accuracy class: 0.5
How to use
The transformer 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 correct orientation relative to the current flow. The secondary terminals should be connected to the measuring or protection device using appropriately sized wiring to minimize resistance and maintain accuracy.
What to consider before purchase
Verify that the primary current matches your specific application requirements.
Ensure the secondary current rating is compatible with your existing metering equipment.
Check the physical dimensions to ensure the unit fits within your electrical cabinet.
Confirm that the accuracy class meets the standards required for your specific metering or protection task.
Usage recommendations
Always ensure that the secondary circuit is connected to a load or short-circuited before energizing the primary conductor to prevent the generation of dangerous high voltages.
