Key specifications

• Transformation ratio: 200/5A
• Rated power: 5VA
• Accuracy class: 0.5
• Application: Low-voltage distribution systems

To use the Eti-Polam CTR-30, mount the transformer securely onto the primary conductor within the electrical panel. Ensure that the primary circuit passes through the aperture of the transformer. Connect the secondary terminals to your measuring device using appropriate wiring, ensuring that the polarity is observed correctly to prevent measurement errors. Always verify that all connections are tightened to the specified torque to maintain electrical integrity.

What to consider before purchase

• Verify that the primary current of your system matches the 200A rating
• Ensure the secondary input of your measuring device is compatible with a 5A signal
• Check available space in the electrical panel for mounting
• Confirm the required accuracy class for your specific metering application

Usage recommendations

Always ensure that the secondary circuit of the current transformer is connected to a load or short-circuited before energizing the primary circuit to prevent the generation of dangerous high voltages.
