ACREL AKH-0.66 G-80i Split-Core Current Transformer
ACREL AKH-0.66 G-80i Split-Core Current Transformer is a clamshell-style current transformer from Acrel's AKH-0.66/G range, built for accurate current measurement in low voltage switchboards and panels. The G-80I fits an 80mm window and is designed to work alongside metering and monitoring instruments.
The ACREL AKH-0.66 G-80i Split-Core Current Transformer is a low voltage current transformer with a transparent polycarbonate flip cover, making secondary wiring easy to inspect. It suits cable or busbar mounting and is commonly paired with energy meters and multifunction meters for current measurement in electrical switchboards.
Full description
How it works
- The transformer clamps around a current-carrying cable or busbar, with the primary conductor passing through the 80mm through-hole.
- It steps the primary current down to a standard secondary output of 5A, matching the current ratio selected (for example, 1000A to 5A).
- The secondary circuit connects to a compatible meter or measuring instrument, which reads and displays the current.
Why choose this product
- The clear polycarbonate cover allows the secondary lead wiring to be checked visually without opening up the unit.
- Fixed installation types A and C give flexibility when mounting to busbars or straight support pieces.
- It's designed to comply with GB 20840.2-2014 current transformer standards and JJG313-2010 verification procedures.
Benefits
- Straightforward installation onto existing cabling or busbar runs.
- Suitable for both technical installers and general electrical maintenance teams.
- A practical option where panel space is tight but reliable current sensing is still needed.
