## Summary description

The Eti-Polam CTR-30 current transformer is designed for precise electrical current measurement in low-voltage systems. It features a 125/5A transformation ratio, 2.5VA power rating, and 0.5 accuracy class. This reliable component is essential for monitoring energy consumption and protecting electrical circuits in industrial and commercial installations.

## Long description

The Eti-Polam CTR-30 current transformer is a precision-engineered device designed for accurate current measurement in low-voltage electrical systems. With a transformation ratio of 125/5A, this component is specifically calibrated to step down high primary currents to a manageable secondary level suitable for measurement instruments and protection relays. Its robust construction ensures consistent performance in demanding industrial and commercial environments, providing reliable data for energy management and circuit monitoring.
Advantages
This current transformer offers high measurement accuracy, which is critical for precise energy billing and system diagnostics. The compact design allows for easy integration into existing electrical panels and switchgear configurations. By utilizing high-quality materials, the device maintains stability under varying load conditions, ensuring long-term operational reliability and minimal maintenance requirements for electrical infrastructure.
Suitable for
Energy consumption monitoring in commercial buildings
Industrial power distribution systems
Integration with ammeters and power meters
Protection relay applications in low-voltage networks
This device is not suitable for high-voltage applications or environments where the primary current exceeds the rated 125A capacity. It should not be used in circuits where the required accuracy class is higher than 0.5 or where the burden exceeds the 2.5VA rating.
Key specifications
Transformation ratio: 125/5A
Accuracy class: 0.5
Rated power: 2.5VA
Application: Low-voltage systems
The transformer is installed by passing the primary conductor through the aperture of the device. The secondary terminals must be connected to the measuring instrument or protection device using appropriate wiring. Ensure that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage spikes.
What to consider before purchase
Verify the primary current of your system matches the 125A rating
Check that the secondary input of your meter is compatible with 5A
Ensure the total burden of the secondary circuit does not exceed 2.5VA
Confirm physical space availability within the electrical cabinet
For optimal performance and safety, ensure all connections are tightened to the manufacturer's specifications and that the secondary circuit is properly grounded according to local electrical regulations.
