Product information

Description

The Lumel LCTB 5030 current transformer is a high-precision device engineered for the accurate measurement of electrical currents in industrial power distribution systems. With a transformation ratio of 150A/5A and a dedicated busbar aperture of 50x30 mm, this transformer facilitates the reliable conversion of high primary currents into manageable secondary signals suitable for monitoring, metering, and protection equipment.

Advantages

This current transformer offers exceptional reliability and consistent performance in demanding electrical environments. Its robust construction ensures long-term stability, while the standardized design allows for seamless integration into existing power infrastructure. The device is specifically optimized for easy mounting on busbars, which significantly reduces installation time and complexity for technical personnel. By providing precise signal transformation, it enhances the overall accuracy of energy management systems and safety relays.

Suitable for

  • Industrial power distribution networks
  • Electrical energy metering systems
  • Protection and monitoring relays
  • Substation current measurement

This device may not be suitable for applications requiring high-frequency current measurement or for environments where the primary conductor dimensions exceed the 50x30 mm aperture limit. It is also not intended for use in high-voltage transmission lines beyond its specified insulation class.

Key specifications

  • Transformation ratio: 150A/5A
  • Busbar aperture dimensions: 50x30 mm
  • Mounting type: Busbar mount
  • Application: Current measurement and signal conversion

To use the Lumel LCTB 5030, ensure the power supply is disconnected before installation. Slide the primary busbar through the 50x30 mm aperture and secure the transformer firmly in place. Connect the secondary terminals to your measuring or protection device using appropriate wiring, ensuring that the polarity is correctly observed to maintain measurement accuracy.

What to consider before purchase

  • Verify that the primary current does not exceed 150A
  • Ensure the busbar dimensions fit within the 50x30 mm opening
  • Confirm compatibility with your secondary measurement equipment
  • Check the environmental conditions of the installation site
For optimal performance, ensure all secondary connections are tightened securely and protected from vibration. Regularly inspect the transformer for signs of physical damage or loose wiring to maintain system integrity.
