## Summary description

The Lumel LCTB 5030 current transformer is designed for precise current measurement in electrical systems. It features a 200A/5A transformation ratio and meets class 0.5 accuracy standards. Equipped with a 50x30mm busbar opening, this device is ideal for industrial power monitoring, energy management, and integration into switchgear panels for reliable secondary current output.

## Long description

The Lumel LCTB 5030 current transformer is a high-precision component engineered for accurate current measurement within electrical distribution systems. With a transformation ratio of 200A/5A and a class 0.5 accuracy rating, this device ensures reliable data acquisition for monitoring and control applications. Its robust construction and 50x30mm busbar opening make it a versatile solution for industrial environments requiring consistent performance in power management.
Advantages
This current transformer offers exceptional measurement precision, which is critical for maintaining efficiency in complex electrical networks. The class 0.5 accuracy ensures that the secondary current output remains proportional and stable, minimizing errors in energy billing or system monitoring. Its physical design allows for straightforward installation on standard busbars, reducing downtime and simplifying the integration process into existing switchgear panels.
Suitable for
Industrial power monitoring systems
Energy management and sub-metering applications
Integration into electrical switchgear panels
Secondary current signal generation for protection relays
This device is not suitable for applications requiring high-voltage insulation beyond its rated specifications or for measuring currents significantly outside the 200A range. It should not be used in environments with extreme electromagnetic interference that could compromise the accuracy of the secondary output.
Key specifications
Transformation ratio: 200A/5A
Accuracy class: 0.5
Busbar opening dimensions: 50x30mm
Application: Industrial electrical systems
To use the Lumel LCTB 5030, mount the transformer securely over the primary conductor busbar, ensuring the orientation matches the required flow direction. Connect the secondary terminals to your measuring or monitoring equipment using appropriately sized wiring. Ensure all connections are tightened to the manufacturer's torque specifications to prevent contact resistance and heat buildup.
What to consider before purchase
Verify that the primary current range of your system matches the 200A rating
Ensure the physical dimensions of your busbar do not exceed the 50x30mm opening
Confirm that your secondary monitoring equipment is compatible with a 5A input
For optimal performance and safety, always ensure that the secondary circuit is never left open while the primary conductor is energized. Regularly inspect the terminals for signs of oxidation or loose connections to maintain measurement accuracy over time.
