Product information

Description

The LCTB 5030 current transformer is a high-precision device engineered for accurate current measurement in electrical distribution systems. Designed with a 50/30mm busbar opening, it facilitates easy integration into existing power infrastructure. This transformer converts high primary currents of 250A into a manageable 5A secondary signal, maintaining a high accuracy class of 0.5 for reliable data acquisition.

Advantages

This current transformer offers exceptional measurement stability and consistent performance across various industrial environments. Its robust construction ensures long-term durability, while the standardized transformation ratio allows for seamless compatibility with a wide range of secondary measuring instruments, such as ammeters, energy meters, and protection relays. The design prioritizes ease of installation, allowing for efficient mounting on busbars without complex modifications to the electrical circuit.

Suitable for

  • Industrial power monitoring systems
  • Energy management and sub-metering applications
  • Electrical protection and control circuits
  • Signal conversion for secondary measuring devices

This device may not be suitable for applications requiring high-voltage insulation beyond its rated specifications or for environments with extreme electromagnetic interference that could compromise signal integrity. It is also not intended for use in circuits where the primary current consistently exceeds the rated 250A capacity.

Key specifications

  • Primary current: 250A
  • Secondary current: 5A
  • Accuracy class: 0.5
  • Busbar opening dimensions: 50/30mm
  • Application: Current measurement and signal conversion

How to use

Installation should be performed by qualified personnel in accordance with local electrical safety standards. The primary conductor (busbar) must be passed through the central opening of the transformer. Ensure the orientation is correct according to the markings on the device casing. Connect the secondary terminals to the measuring instrument or protection relay using appropriate cross-section wiring to minimize resistance and signal loss. Verify all connections are secure before energizing the circuit.

What to consider before purchase

  • Ensure the busbar dimensions are compatible with the 50/30mm opening
  • Verify that the 250A/5A transformation ratio matches your system requirements
  • Check the accuracy class requirements for your specific monitoring or billing application
  • Confirm the physical space availability in the electrical cabinet for mounting

Usage recommendations

Regularly inspect the secondary connections for tightness and ensure the device remains free from dust and moisture accumulation to maintain optimal measurement accuracy over time.
