It is also not intended for use with cables exceeding the specified 21mm diameter or for high-voltage transmission lines outside its rated operational range.

Key specifications

• Transformation ratio: 50/5A
• Power rating: 1.25VA
• Accuracy class: 1
• Instrument security factor: FS5
• Maximum cable diameter: 21mm

Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The transformer is mounted directly onto the primary conductor. Ensure that the cable is centered within the aperture to maintain measurement accuracy. Connect the secondary terminals to the appropriate metering or protection devices using correctly sized wiring to prevent signal loss or measurement errors.

What to consider before purchase

• Verify the primary current requirements of your installation
• Ensure the cable diameter does not exceed 21mm
• Check compatibility with your existing metering or protection equipment
• Confirm that the accuracy class meets your specific application needs

For optimal performance and safety, ensure all secondary connections are tightened securely and that the transformer is protected from excessive vibration or extreme thermal conditions during operation.
