FF TOM-200-5 Miniature Split-Core Current Transformer 200/5A 1.5VA

The FF TOM-200-5 is a high-precision miniature split-core current transformer engineered for reliable current measurement in electrical systems. With a transformation ratio of 200/5A and a power rating of 1.5VA, this device provides accurate data for monitoring and control applications. Its compact split-core design is specifically intended for environments where space is at a premium, allowing for seamless integration into existing infrastructure.

Advantages

The primary benefit of this current transformer is its split-core architecture, which enables installation directly onto live cables without the need to disconnect or interrupt the primary circuit. This feature significantly reduces downtime and labor costs during setup. Its miniature size ensures it can be fitted into crowded electrical panels or tight enclosures where standard transformers would not fit. Furthermore, the robust construction ensures consistent performance and measurement accuracy over extended periods of operation.

Suitable for

• Energy monitoring and management systems
• Sub-metering applications
• Industrial automation and control processes
• Electrical load analysis

When it may not be suitable

This transformer is not designed for high-voltage power distribution networks or applications requiring a transformation ratio other than 200/5A. It should not be used in environments that exceed its specified power rating or in conditions where the cable diameter exceeds the physical aperture of the split-core opening.

Key specifications

• Transformation ratio: 200/5A
• Power rating: 1.5VA
• Design: Split-core
• Application: Miniature current measurement

How to use

To install the device, open the split-core mechanism by releasing the latch. Position the transformer around the conductor carrying the current to be measured and snap the core shut until it clicks securely into place. Ensure that the polarity is observed according to the system requirements. Connect the secondary terminals to your measuring instrument or energy meter using appropriate wiring. Verify that the connection is stable and that the transformer is properly secured to prevent movement.

What to consider before purchase

• Verify that the primary current of your circuit does not exceed 200A
• Check that the physical diameter of your cable fits within the transformer aperture
• Ensure your measuring equipment is compatible with a 5A secondary output

Usage recommendations

Always ensure that the secondary circuit is connected to a load or shorted before energizing the primary circuit to prevent high voltage buildup. Regular inspection of the latch mechanism is recommended to ensure the core remains tightly closed for optimal accuracy.
