ACREL AKH-0.66 P-80 x 50ii Protection Current Transformer
ACREL AKH-0.66 P-80 x 50ii Protection Current Transformer is a protection current transformer for low-voltage protection circuits. It features an 82 mm x 52 mm through opening and supports a range of rated current ratios with 5P5, 5P10 and 5P15 protection accuracy options. It is designed for protection applications involving busbars and multiple conductors.
The ACREL AKH-0.66 P-80 x 50ii Protection Current Transformer is designed specifically for protection applications rather than general current measurement. Acrel states that the series is developed for protection systems that detect short circuit and overload current, with different accuracy levels and accuracy limit coefficients available for selection.
The P-80 x 50II version has an 82 mm x 52 mm through opening and is designed for installation around suitable busbar arrangements. The manufacturer provides current ratio and protection accuracy combinations for this model, including 200 to 300 A, 400 to 600 A, 800 to 2000 A and 2500 A primary current ranges.
How it works
- The current transformer is installed around the applicable busbar or conductors.
- Primary current passing through the transformer produces a corresponding secondary current.
- The secondary output can be connected to a suitable protection relay or protection system.
- The protection system can use the current signal to detect abnormal current conditions such as overloads or short circuits.
Why choose this product
- Designed specifically for protection circuit applications.
- Available with multiple current ratios for different system requirements.
- Provides 5P5, 5P10 and 5P15 protection accuracy options for the P-80 x 50II configuration.
- The 82 mm x 52 mm through opening accommodates the specified busbar arrangement.
- Suitable for low-voltage distribution protection applications.
Benefits
- Provides current sensing for protection systems.
- Supports selection based on required protection accuracy and rated current.
- Suitable for applications requiring current transformer protection characteristics rather than standard measurement CT performance.
- Can be used with protection equipment where the selected transformer ratio and accuracy class meet the system requirements.
