Product information

Description

The Lumel LCTB 7440 current transformer is a high-precision component engineered for the reliable measurement of alternating current in electrical distribution systems. Designed specifically for busbar mounting, this device features a 74/40 mm aperture, allowing for seamless integration into existing power infrastructure. It effectively transforms high primary currents into a manageable 5A secondary signal, making it an essential tool for accurate monitoring and energy management.

Advantages

This current transformer offers exceptional measurement accuracy, ensuring that secondary devices receive precise data for monitoring and control purposes. Its robust construction is designed to withstand the rigors of industrial environments, providing long-term stability and consistent performance. The busbar-mounted design simplifies the installation process, reducing downtime and labor costs during system upgrades or maintenance. By converting high currents into standard secondary values, it ensures compatibility with a wide range of measuring instruments and protection relays.

Suitable for

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

This device may not be suitable for applications involving direct current (DC) measurement, as it is specifically designed for alternating current (AC) systems. It is also not intended for use in high-voltage transmission lines exceeding its specified insulation class or in environments where the busbar dimensions exceed the 74/40 mm aperture capacity.

Key specifications

  • Transformation ratio: 200A/5A
  • Busbar aperture: 74/40 mm
  • Mounting type: Busbar
  • Application: AC current measurement

To use the Lumel LCTB 7440, ensure the electrical system is de-energized before installation. Slide the transformer over the primary busbar, ensuring the orientation matches the required current flow direction. Secure the device firmly using the provided mounting hardware. Connect the secondary terminals to your measuring instrument or energy meter using appropriately sized wiring, ensuring all connections are tight and compliant with local electrical safety standards.

What to consider before purchase

  • Verify that the primary current of your system matches the 200A rating
  • Check that your busbar dimensions fit within the 74/40 mm opening
  • Ensure compatibility with your secondary measuring equipment's input requirements
  • Confirm the environmental conditions are within the manufacturer's specified operating range

Usage recommendations

Always ensure that the secondary circuit of the current transformer is connected to a load or short-circuited before energizing the primary circuit to prevent dangerous voltage build-up.
