Suitable for

• Industrial power distribution monitoring
• Energy metering systems
• Electrical protection and relay coordination
• Substation current measurement

This device may not be suitable for applications requiring high-frequency current measurement or for use in environments where the primary conductor dimensions exceed the 80x160mm aperture limit. It is also not intended for direct connection to low-voltage consumer electronics without appropriate secondary instrumentation.

Key specifications

• Transformation ratio: 2000/5A
• Aperture dimensions: 80x160mm
• Width: 225 mm
• Depth: 250 mm
• Height: 90 mm

To use the IME S.p.A. TA81650D200, mount the transformer securely over the primary conductor, ensuring the busbar passes cleanly through the 80x160mm aperture. Connect the secondary terminals to the input of your metering or protection device using appropriate gauge wiring. Ensure all connections are tightened to the specified torque to prevent contact resistance and signal loss. Always verify that the polarity markings are correctly aligned with the direction of the current flow to ensure accurate readings.

What to consider before purchase

• Verify that the primary current does not exceed the rated 2000A capacity.
• Ensure the physical dimensions of the busbar are compatible with the 80x160mm aperture.
• Confirm that your secondary instrumentation is calibrated for a 5A input.
• Check the available space in your electrical panel against the unit's dimensions of 225x250x90mm.

Usage recommendations: Always perform installation while the circuit is de-energized to ensure safety. Regularly inspect the secondary connections for signs of oxidation or looseness to maintain measurement accuracy over time.
