FF TO-1000-5 Split-Core Current Transformer 1000/5A Class 0.5

The FF TO-1000-5 is a high-precision split-core current transformer engineered for accurate electrical current measurement in systems up to 1000A, providing a reliable 5A secondary output. Designed for seamless integration into existing electrical infrastructure, this device facilitates precise monitoring and power management without the need to interrupt the primary circuit.

Advantages

The primary benefit of this split-core current transformer is its ability to be installed on live cables, which significantly reduces downtime and labor costs during system upgrades or maintenance. With a class 0.5 accuracy rating, it ensures high-precision data acquisition essential for energy auditing and billing applications. Its robust construction and compact design make it a versatile solution for various industrial and commercial environments where space and efficiency are critical.

Suitable for

• Energy monitoring and management systems
• Industrial power distribution networks
• Commercial building energy audits
• Retrofitting existing electrical installations
• Sub-metering applications

When it may not be suitable

This device is not intended for use in high-voltage transmission lines or environments exceeding its specified current rating. It is also not suitable for applications requiring direct measurement of DC currents, as it is designed exclusively for AC systems.

Key specifications

• Primary current: 1000A
• Secondary output: 5A
• Accuracy class: 0.5
• Design: Split-core
• Application: AC current measurement

How to use

Installation involves opening the split-core housing and placing it around the primary conductor. Once positioned, the core should be securely closed to ensure proper magnetic coupling. The secondary terminals are then connected to the measuring device or energy meter using appropriate wiring, ensuring that the polarity is observed to maintain measurement accuracy.

What to consider before purchase

• Ensure the primary cable diameter fits within the transformer aperture
• Verify that the secondary output matches the input requirements of your measuring device
• Confirm the system operates within the specified AC frequency range

Usage recommendations

For optimal performance and safety, ensure all connections are tight and the transformer is mounted in a location free from excessive vibration or extreme temperatures. Regular inspection of the core closure is recommended to maintain measurement precision.
