Product information

Description

The LOVATO Electric DM3T0300 is a high-precision current transformer engineered for accurate electrical measurement and monitoring in industrial power distribution systems. This device is designed to step down high primary currents to a manageable secondary current of 5A, facilitating the use of standard measuring instruments and protection relays. With its robust construction and versatile mounting options, it provides a reliable solution for energy management and grid monitoring applications.

Advantages

This current transformer offers exceptional measurement accuracy, meeting the requirements of class 0.5 standards, which ensures precise data for billing and system analysis. Its design allows for flexible installation, accommodating both cable and various busbar configurations, which simplifies integration into existing electrical panels. The compact build and high-quality materials ensure long-term stability and performance even in demanding industrial environments, reducing the need for frequent maintenance or recalibration.

Suitable for

  • Industrial power distribution monitoring
  • Energy management and sub-metering systems
  • Protection relay applications
  • Electrical panel instrumentation

This transformer may not be suitable for high-voltage applications exceeding its rated insulation levels or for environments with extreme electromagnetic interference that could compromise measurement accuracy. It is also not intended for use in circuits where the primary current consistently exceeds the specified transformation ratio.

Key specifications

  • Transformation ratio: 300/5A
  • Accuracy class: 0.5
  • Power rating: 2.5VA
  • Maximum cable diameter: 30mm
  • Busbar compatibility: 40x10mm, 20x30mm, 25x25mm

To use the LOVATO Electric DM3T0300, ensure the primary conductor passes through the center of the transformer aperture. Secure the device firmly using the provided mounting accessories to prevent vibration or movement. Connect the secondary terminals to your measuring device or relay using appropriately sized wiring, ensuring that the polarity is correctly observed to maintain measurement accuracy. Always verify that the secondary circuit is never left open while the primary circuit is energized.

What to consider before purchase

  • Verify the primary current of your system matches the 300A rating
  • Check the physical dimensions of your cables or busbars against the aperture size
  • Ensure the secondary load does not exceed the 2.5VA power rating
  • Confirm the required accuracy class for your specific application
For optimal performance, ensure that all electrical connections are tightened to the manufacturer's specifications and that the transformer is installed in a location free from excessive heat or moisture. Regular inspection of the secondary wiring is recommended to ensure system integrity.
