Product information

Description

The Lumel LCTR 4514400030A51 is a high-precision current transformer designed for accurate current measurement and monitoring in industrial electrical systems. Featuring a robust round aperture design, this device facilitates the safe and reliable conversion of high primary currents into a standardized secondary signal suitable for various measuring instruments. It is engineered to maintain signal integrity and performance in demanding power distribution environments.

Advantages

This current transformer offers exceptional measurement accuracy, ensuring that secondary devices receive precise data for monitoring and control purposes. Its durable construction is specifically tailored for industrial use, providing long-term reliability and consistent performance. The round aperture design simplifies the installation process, allowing for efficient integration into existing electrical panels and power distribution setups without requiring complex modifications.

Suitable for

  • Industrial power distribution systems
  • Electrical energy monitoring and management
  • Secondary signal conversion for measuring instruments
  • Current measurement in low-voltage electrical circuits

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

Key specifications

  • Transformation ratio: 30A/5A
  • Aperture type: Round
  • Application: Industrial electrical systems
  • Function: Current measurement and signal conversion

To use the Lumel LCTR 4514400030A51, pass the primary conductor through the round aperture of the transformer. Ensure that the secondary terminals are correctly connected to the measuring instrument or relay. It is essential to maintain proper polarity during installation to ensure accurate readings and system safety. Always verify that the secondary circuit is closed before energizing the primary conductor to prevent high voltage buildup.

What to consider before purchase

  • Verify the primary current range of your application matches the 30A rating
  • Ensure the physical dimensions of the aperture accommodate your conductor size
  • Confirm compatibility with your existing secondary measuring equipment
For optimal performance and safety, ensure all connections are tightened to the manufacturer's specifications and that the device is installed by qualified personnel in accordance with local electrical regulations.
