ACREL AC Current Transformer for Cable and Busbar Measurement 30I

The ACREL AC Current Transformer for Cable and Busbar Measurement 30I is designed for AC current measurement in electrical distribution and monitoring systems. It works with measuring instruments by collecting the AC current signal from the primary circuit and providing a lower secondary current for measurement.

The series covers primary current ratios from 15 A to 3000 A, depending on the selected configuration. Secondary outputs are available as 5 A or 1 A, with the manufacturer's product page specifying a measurement range of 5-120% of the rated value.

The transformer is available in 30I, 40I, 60I and 80I physical configurations. The different sizes provide different cable through-holes and busbar arrangements, allowing the appropriate version to be selected according to the conductor dimensions and required current ratio.

How it works

• The primary conductor passes through the current transformer's opening.
• The transformer senses the AC current flowing through the primary circuit.
• Electromagnetic induction produces a proportional secondary current.
• The secondary output is provided as 5 A or 1 A for connection to compatible measuring instruments or energy meters.

Why choose this product

• Available across a wide range of primary current ratios from 15 A to 3000 A.
• Multiple physical sizes are available to suit different cable and busbar arrangements.
• The clamshell construction provides convenient access for installation and wiring.
• The transparent polycarbonate cover allows the secondary lead wiring to be viewed.

Benefits

• Provides a practical interface between high-current circuits and compatible measurement equipment.
• Supports AC current monitoring in power distribution applications.
• Allows current measurement without routing the full primary current directly through the measuring instrument.
• Multiple current ratios and physical configurations provide flexibility when specifying a current transformer.
