## Long description

The Eti-Polam CTR-30 current transformer is a high-precision component engineered for accurate electrical current measurement within low-voltage distribution networks. Featuring a transformation ratio of 200/5A and a rated power of 5VA, this device is specifically designed to convert high primary currents into manageable secondary signals suitable for standard measuring instruments. Its robust construction ensures consistent performance in demanding industrial and commercial electrical environments.
Advantages
This current transformer offers exceptional reliability and precision, maintaining an accuracy class of 0.5 to ensure that monitoring and metering data remain dependable. The compact design allows for efficient installation within electrical panels, saving valuable space while maintaining high operational standards. By providing stable signal conversion, it facilitates the seamless integration of various analytical tools and energy management systems into existing electrical infrastructure.
Suitable for
Energy monitoring and sub-metering in commercial buildings
Industrial power distribution panels
Current signal conversion for analog and digital ammeters
Integration with power quality analyzers
This device is not intended for high-voltage applications or environments where the primary current consistently exceeds the specified transformation ratio. It is also not suitable for direct connection to high-power loads without appropriate secondary measuring equipment.
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.
