When it may not be suitable
This transformer is not intended for high-voltage applications exceeding its specified insulation levels. It is also not suitable for measuring currents outside the 100A primary range, as this would compromise accuracy and potentially damage the connected secondary equipment.
Key specifications
Transformation ratio: 100/5A
Rated power: 1.5VA
Accuracy class: 0.5
Application: Current measurement and monitoring
How to use
The current transformer should be installed by a qualified professional in accordance with local electrical safety regulations. The primary conductor must be passed through the aperture of the transformer, ensuring proper orientation as indicated by the device markings. The secondary terminals must be connected to the corresponding metering or protection equipment using appropriately sized wiring. Ensure all connections are secure and that the secondary circuit is never left open while the primary circuit is energized.
What to consider before purchase
Verify that the transformation ratio matches your specific load requirements
Ensure the secondary equipment is compatible with a 5A output
Check the available space in your electrical cabinet for mounting
Confirm that the accuracy class meets your regulatory or operational needs
Usage recommendations
Always ensure the secondary circuit is connected to a load or short-circuited before energizing the primary conductor to prevent dangerous voltage buildup.
