This robust component is essential for accurate energy management and electrical network protection.

## Long description

The Eti-Polam CTR-30 current transformer is a precision-engineered device specifically designed for the accurate measurement of electrical currents within industrial and commercial power distribution systems. By converting high primary currents into a manageable secondary signal, this transformer facilitates precise monitoring and metering, ensuring that energy management systems receive reliable data for billing and network analysis.
Advantages
This current transformer offers exceptional reliability and consistent performance in demanding electrical environments. Its high-precision design ensures minimal signal distortion, which is critical for maintaining the integrity of connected metering equipment. The robust construction provides long-term durability, while the standardized transformation ratio allows for seamless integration into existing electrical infrastructures, supporting efficient energy management and enhanced protection of power networks.
Suitable for
Industrial power distribution monitoring
Commercial energy metering systems
Electrical network protection circuits
Sub-metering applications for energy management
This device may not be suitable for high-voltage transmission lines or applications requiring a transformation ratio other than 300/5A. It is also not intended for use in environments where the rated power capacity of 10VA is exceeded, as this would compromise the accuracy and safety of the measurement.
Key specifications
Transformation ratio: 300/5A
Rated power: 10VA
Accuracy class: 0.5
Application: Current measurement and monitoring
To use the Eti-Polam CTR-30, it must be installed by a qualified professional in accordance with local electrical safety regulations. The primary conductor should be passed through the aperture of the transformer, ensuring proper orientation. The secondary terminals must be connected to the corresponding metering or protection devices using appropriately sized wiring to minimize resistance and maintain the specified accuracy class.
What to consider before purchase
Verify that the 300/5A transformation ratio matches your system requirements
Ensure the 10VA power rating is sufficient for your connected load
Confirm the physical dimensions are compatible with your installation space
Check that the accuracy class 0.5 meets your specific metering standards
Usage recommendations
Always ensure that the secondary circuit of the current transformer is never left open while the primary circuit is energized, as this can lead to dangerous voltage levels and damage to the device.
