FF TO-1500-5 Split-Core Current Transformer 1500/5A Class 0.5

The FF TO-1500-5 is a high-precision split-core current transformer engineered for efficient electrical monitoring. Designed with a transformation ratio of 1500/5A and an accuracy class of 0.5, this device provides reliable data for power management systems. Its split-core architecture allows for installation directly onto existing cables without the need to disconnect or interrupt the primary electrical circuit, making it an essential tool for retrofitting and maintenance projects.

Advantages

The primary benefit of this current transformer is its non-invasive installation process, which significantly reduces downtime and labor costs during setup. By eliminating the need to cut or disconnect primary conductors, it ensures safety and operational continuity. The high accuracy class of 0.5 guarantees precise measurements, which are critical for accurate energy billing, sub-metering, and load analysis in demanding industrial and commercial environments.

Suitable for

• Energy monitoring and sub-metering systems
• Power management and load analysis
• Retrofitting existing electrical infrastructure
• Industrial and commercial energy audits

When it may not be suitable

This device is not intended for use in high-voltage transmission lines or environments where the primary current consistently exceeds the rated 1500A capacity. It is also not suitable for applications requiring direct contact with bare conductors without proper insulation.

Key specifications

• Transformation ratio: 1500/5A
• Accuracy class: 0.5
• Design: Split-core for non-invasive mounting
• Application: Current measurement for monitoring systems

How to use

To install the transformer, open the split-core housing by releasing the locking mechanism. Place the device around the primary conductor and snap the core halves securely shut, ensuring the surfaces are clean and properly aligned to maintain measurement accuracy. Connect the secondary terminals to your measuring instrument or energy meter using appropriate wiring. Ensure that the polarity is observed correctly during connection to avoid measurement errors.

What to consider before purchase

• Verify that the primary current does not exceed 1500A
• Ensure the secondary input of your meter is compatible with 5A signals
• Check the physical dimensions of the cable to ensure it fits within the transformer aperture

Usage recommendations

Always ensure that the secondary circuit is connected to a load or shorted before energizing the primary conductor to prevent high voltage buildup. Regular inspection of the core closure is recommended to maintain optimal accuracy.
