Suitable for
Industrial power distribution systems
Commercial building energy monitoring
Protection relay applications
Electrical panel instrumentation
Current measurement in busbar configurations
When it may not be suitable
This device is not intended for use in high-voltage transmission lines or environments exceeding its specified insulation and thermal limits. It is also not suitable for applications requiring a transformation ratio other than 400A/5A or for installations where the physical dimensions of the busbar exceed the aperture capacity of the transformer.
Key specifications
Transformation ratio: 400A/5A
Accuracy class: 0.5
Mounting type: Busbar
Aperture size: 104/60 mm
How to use
To install the LCTB 104/60 current transformer, ensure that the primary power circuit is de-energized to prevent electrical hazards. Pass the busbar through the central aperture of the transformer, ensuring it is centered and securely fastened according to the mechanical mounting instructions. Connect the secondary terminals to the measuring or protection device using appropriate wiring, ensuring correct polarity. Once installed, verify all connections before re-energizing the primary circuit to ensure accurate readings.
What to consider before purchase
Verify that the primary current of your system matches the 400A rating.
Ensure the busbar dimensions are compatible with the 104/60 mm aperture.
Confirm that the accuracy class 0.5 meets your specific monitoring requirements.
Check the space availability within the electrical cabinet for proper mounting.
Usage recommendations: Always ensure that the secondary circuit of the current transformer is never left open while the primary circuit is energized, as this can lead to dangerous high-voltage build-up. Regularly inspect the connections for tightness and signs of thermal stress to maintain optimal performance.
