ACREL AKH-0.66 P-130 x 50ii Protection Current Transformer
ACREL AKH-0.66 P-130 x 50ii Protection Current Transformer is a protection current transformer for low-voltage power distribution and relay protection circuits. It is designed for busbar installation and is available with multiple current ratios and protection accuracy classes, including 5P5, 5P10, 5P15 and 5P20. The P-130 x 50II model supports busbars up to 130 x 10 mm, depending on the installation arrangement.
The ACREL AKH-0.66 P-130 x 50ii Protection Current Transformer is part of Acrel's AKH-0.66/P range of protection current transformers. The series is designed for relay protection circuits where the current transformer provides the current signal required to detect abnormal operating conditions.
The P-130 x 50II model has a 220 mm W x 177 mm H x 75 mm D overall size and a 131 mm x 51 mm through-opening according to Acrel's published dimensional information. The manufacturer specifies a mounting dimension of 170 mm for this model.
How it works
- The primary conductor or busbar passes through the current transformer's opening.
- The transformer converts the primary current into a proportional secondary current for use by protection equipment.
- The protection circuit can use this signal to identify conditions such as overload or short circuit current.
- The P-130 x 50II version uses one straight-through turn for the specified busbar configurations.
Why choose this product
- Designed specifically for protection applications rather than general-purpose current measurement.
- Available across a range of rated current ratios from 600/5 to 5000/5, depending on the selected configuration.
- Supports several protection accuracy classes, allowing selection according to the protection circuit requirements.
- Suitable for larger busbar installations within the manufacturer's specified dimensions.
- Part of Acrel's AKH-0.66/P protection current transformer range.
Benefits
- Provides a dedicated current signal for electrical protection systems.
- Supports flexible selection of current ratio and protection accuracy.
- The busbar configuration allows installation around suitable existing conductors.
- The range of available protection classes provides options for different relay protection requirements.
