ACREL AKH-0.66 80iii AC Current Transformer
ACREL AKH-0.66 80iii AC Current Transformer is a vertical square-hole AC current transformer for low voltage electrical measurement and metering. It accommodates busbars up to 80 mm by 10 mm and can be configured for selected primary current ratios from 300 A to 3000 A. The transformer provides a 5 A or 1 A secondary output according to the selected ratio and is available with Class 0.2 or Class 0.5 accuracy options.
The ACREL AKH-0.66 80iii AC Current Transformer has an external size of 117 mm by 167 mm by 55 mm and a 52 mm by 82 mm through opening for the conductor or busbar arrangement.
The transformer is intended to convert the current flowing through a primary conductor into a corresponding secondary current for measurement. This allows compatible meters and measuring instruments to monitor electrical current without directly measuring the full primary current.
How it works
- The primary conductor or busbar passes through the transformer opening.
- The AC current produces a magnetic field within the transformer core.
- The transformer provides a proportional secondary current for connection to compatible measuring equipment.
- The 80III configuration supports 1 to 3 busbars according to the manufacturer's specifications.
Why choose this product
- Designed specifically for AC current measurement and electrical metering.
- Square-hole construction accommodates busbar installations.
- Multiple primary current ratios are available within the 80III specification range.
- Secondary output can be selected as 5 A or 1 A depending on the specified current ratio.
- Available with Class 0.2 or Class 0.5 accuracy for applicable configurations.
Benefits
- Provides an isolated measurement interface between high-current conductors and compatible measuring equipment.
- Supports installation around existing busbar arrangements without requiring the current to pass directly through a measuring instrument.
- The transparent cover allows the secondary lead connection to be viewed, according to Acrel's product description.
