Eti-Polam CTR-30 Current Transformer 300/5A 10VA Class 0.5

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.
