ACREL AKH-0.66 P-180 x 50ii Protection Current Transformer

The ACREL AKH-0.66 P-180 x 50ii Protection Current Transformer is designed for current measurement associated with electrical protection systems. Its through-type construction provides a practical method of sensing current from a busbar or conductor while providing a secondary output suitable for compatible protection equipment.

The P-180 x 50II version has a relatively large through opening, making it suitable for electrical assemblies where the conductor or busbar arrangement requires additional clearance. Acrel documentation specifies the model with primary current ratios from 1200 A to 5000 A, depending on the selected accuracy and burden configuration.

How it works

• The primary conductor or busbar passes through the transformer's central opening.
• Current flowing through the primary conductor produces a corresponding current in the secondary winding.
• The transformed secondary current can be connected to compatible protection equipment for electrical system monitoring and protection.
• The required current ratio and protection accuracy should be selected according to the application and connected equipment.

Why choose this product

• Designed specifically for protection current transformer applications.
• Large through opening suitable for compatible high-current busbar arrangements.
• Available with multiple rated current ratio options.
• Provides 5P protection accuracy options documented by the manufacturer.
• Suitable for integration into compatible low voltage electrical protection systems.

Benefits

• Enables current sensing without incorporating the primary conductor into the transformer winding.
• Supports protection equipment requiring a current transformer input.
• Provides a practical through-type construction for electrical switchboard and distribution applications.
• Different ratio and accuracy options allow selection according to the protection system requirements.
