ACREL AKH-0.66S S-30I Dual-Winding Current Transformer

The ACREL AKH-0.66S S-30I Dual-Winding Current Transformer combines two secondary windings in one current transformer. The first secondary winding is intended for current indication and can have a rated secondary current of 5 A or 1 A. The second secondary winding provides a 20 mA output for remote measurement and can be used with compatible monitoring equipment such as the ARTU-M32 remote measurement unit or ARD3 motor protector.

The S-30I configuration has a 22 mm aperture and is available with different primary current ratios. The manufacturer's specifications list ratios from 5/5(1)/0.02 through to 200/5(1)/0.02, with the applicable accuracy class and burden depending on the selected ratio.

How It Works

• The primary conductor passes through the current transformer aperture.
• The transformer converts the primary current into lower secondary current signals.
• The first secondary winding provides a standard 5 A or 1 A signal for current indication.
• The second secondary winding provides a 20 mA signal for remote measurement.
• The dual-winding arrangement allows current indication and remote monitoring to be handled from the same transformer.

Why Choose This Product

• Dual secondary windings provide separate outputs for indication and remote monitoring.
• The S-30I format is suitable for conductors passing through a 22 mm aperture.
• Multiple primary current ratios are available within the S-30I range.
• The 20 mA secondary output can be used with compatible Acrel monitoring equipment.
• The manufacturer specifies the AKH-0.66S series for motor protection circuits.

Benefits

• Supports both local current indication and remote measurement.
• Provides a compact current transformer arrangement for monitoring systems.
• Allows the primary current ratio to be selected to suit the intended measurement application.
• Suitable for integration with compatible electrical monitoring and protection equipment.
