FF TOM-500-5 Miniature Split-Core Current Transformer 500/5A 1.5VA

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.
