## Long description

The Lumel LCTB 6230400125A55 is a high-precision current transformer engineered for accurate electrical monitoring in industrial environments. This device is designed to step down high primary currents to a manageable secondary level, facilitating precise measurement and analysis within energy management systems and electrical switchgear. With its robust construction and reliable performance, it ensures consistent data acquisition for various power distribution applications.
Advantages
This current transformer offers exceptional measurement accuracy, adhering to the 0.5 class standard, which is essential for billing and precise energy monitoring. Its design allows for straightforward installation on busbars, saving time during setup in complex electrical panels. The durable housing protects the internal components from environmental factors, ensuring a long service life and stable operation even in demanding industrial conditions.
Suitable for
Energy management and monitoring systems
Industrial electrical switchgear
Power distribution panels
Current measurement for secondary control devices
When it may not be suitable
This device is not intended for use in high-voltage transmission lines or applications requiring a transformation ratio other than 125/5A. It is also not suitable for outdoor environments without additional protective enclosures to prevent moisture or dust ingress.
Key specifications
Transformation ratio: 125/5A
Accuracy class: 0.5
Power rating: 1.5VA
Busbar aperture: 62/30mm
How to use
The transformer is mounted directly onto the busbar through the provided aperture. Ensure the primary conductor passes through the center of the aperture for optimal accuracy. Connect the secondary terminals to your measuring instrument or energy meter using appropriate wiring, ensuring that the polarity is correctly observed to prevent measurement errors. Always ensure the system is de-energized before installation.
What to consider before purchase
Verify that the primary current of your system matches the 125A rating.
Check the physical dimensions of your busbar to ensure it fits the 62/30mm aperture.
Confirm that the 1.5VA burden is sufficient for your connected measuring equipment.
Usage recommendations
Always ensure that the secondary circuit is never left open while the primary circuit is energized, as this can lead to dangerous voltage levels and damage to the transformer.
