ACREL 80II Current Transformer for Electrical Monitoring

The ACREL 80II Current Transformer for Electrical Monitoring provides an isolated secondary current signal for AC current measurement. Its solid-core construction and horizontal square-hole arrangement allow the primary conductor to pass through the transformer, making it suitable for measurement installations involving busbars and multiple cables.

For the 80II size, the manufacturer specifies an 82 x 32 mm through opening, providing a defined space for the primary conductor arrangement. The overall dimensions are 117 x 119 x 45 mm, with a mounting dimension of 60 mm and a 5 mm mounting hole.

The available 80II ratios cover a broad range of primary currents. The specified accuracy and rated burden vary with the selected ratio, so the exact ratio should be matched to the intended measuring circuit.

How it works

• The primary busbar or cable passes through the transformer's central opening.
• AC current flowing through the primary conductor produces a corresponding magnetic field in the transformer core.
• The transformer provides a proportional secondary current for connection to compatible electrical measuring equipment.
• The 80II configuration uses a horizontal square through-hole design for the primary conductor.

Why choose this product

• Solid-core construction for fixed measurement installations.
• 82 x 32 mm through opening for the 80II version.
• Multiple primary current ratios are available within the 80II specification.
• Designed for use with electrical measuring instruments.
• Suitable for busbar and multiple-cable measurement arrangements.

Benefits

• Provides a practical method of obtaining an AC current measurement signal.
• The range of ratios allows the transformer to be matched to different primary current levels.
• The horizontal opening provides a defined installation space for the primary conductor.
• Compact 117 x 119 x 45 mm dimensions for the 80II version can assist with equipment layout.
