## Summary description

The FF TOM-500-5 is a miniature split-core current transformer designed for precise current measurement. It features a 500/5A transformation ratio and a 1.5VA power rating. The split-core design allows for easy installation on existing cables without disconnecting the primary circuit. Ideal for energy monitoring, sub-metering, and industrial automation applications where space is limited and efficiency is required.

## Long description

The FF TOM-500-5 is a high-precision miniature split-core current transformer engineered for reliable current monitoring in electrical systems. With a transformation ratio of 500/5A and a power rating of 1.5VA, this device provides accurate data for energy management and sub-metering applications. Its compact split-core design is specifically developed to facilitate installation in environments where space is at a premium, allowing for integration into existing setups without the need to disconnect primary circuit wiring.
Advantages
The primary benefit of the FF TOM-500-5 lies in its split-core architecture, which significantly reduces installation time and labor costs by eliminating the requirement to shut down or disconnect power lines. This transformer offers high measurement accuracy while maintaining a small physical footprint, making it an ideal solution for retrofitting existing electrical panels. Its robust construction ensures long-term stability and consistent performance in demanding industrial and commercial environments.
Suitable for
Energy monitoring and sub-metering systems
Industrial automation and control panels
Retrofitting existing electrical installations
Load management and power quality analysis
This transformer may not be suitable for high-voltage applications exceeding its specified insulation ratings or for environments with extreme electromagnetic interference that could compromise measurement accuracy. It is also not intended for use in circuits where the primary current consistently exceeds the rated 500A capacity.
Key specifications
Transformation ratio: 500/5A
Power rating: 1.5VA
Design: Split-core
Application: Current measurement
To install the FF TOM-500-5, simply open the split-core housing, place it around the conductor carrying the primary current, and securely snap the core shut. Ensure that the transformer is properly oriented according to the flow of current. Once closed, connect the secondary terminals to your measuring device or power meter, ensuring all connections are tight and secure to prevent signal loss or measurement errors.
What to consider before purchase
Verify that the primary current does not exceed 500A
Ensure the physical dimensions of the cable fit within the aperture
Confirm compatibility with your secondary measuring equipment
Check that the installation environment meets the required safety standards
Usage recommendations
For optimal accuracy, ensure the primary conductor is centered within the aperture of the transformer. Regularly inspect the connection points to ensure they remain free of oxidation and debris, which can affect the integrity of the secondary signal.
