ACREL AKH-0.66 G-170x100II Closed Core AC Current Transformer
ACREL AKH-0.66 G-170x100II Closed Core AC Current Transformer is a closed core AC current transformer for electrical current measurement. It features a 170 x 100 mm opening and supports primary current ratings from 10 A to 5000 A with a 5 A secondary output. It is suitable for use with measuring instruments and electrical equipment where AC current needs to be monitored or measured.
The ACREL AKH-0.66 G-170x100II Closed Core AC Current Transformer is designed to acquire AC current signals for use with measuring instruments and electrical monitoring equipment. Its large rectangular opening provides space for busbar installation and allows the transformer to be incorporated into electrical distribution and measurement systems.
The manufacturer identifies the G series as a vertical square hole type that can accommodate busbars and can also be used for electrical metering and protection applications when matched with suitable equipment.
How it works
- The primary conductor or busbar passes through the current transformer opening.
- The transformer converts the primary AC current into a proportional secondary current.
- The 5 A secondary output can be connected to compatible measuring or monitoring equipment.
- The selected transformation ratio and accuracy class should match the requirements of the measurement system.
Why choose this product
- Designed specifically for AC current measurement.
- Large 170 x 100 mm opening accommodates larger busbar arrangements.
- Available with primary current ratings covering 10 A to 5000 A.
- Provides a standard 5 A secondary current for compatible measurement equipment.
- Available in multiple accuracy classes according to the manufacturer's specifications.
Benefits
- Supports electrical current monitoring without directly connecting the measuring instrument to the primary circuit.
- Suitable for integration with compatible electrical measurement equipment.
- The closed core construction provides a fixed transformer arrangement for installed measurement systems.
- The range of primary current ratings allows selection according to the electrical system being measured.
