ACREL AKH-0.66 G-180x50ii Closed Core AC Current Transformer

The ACREL AKH-0.66 G-180x50ii Closed Core AC Current Transformer is a metering-type AC current transformer designed to convert high AC current into a lower secondary current for use with compatible electrical measuring equipment. The manufacturer lists primary current ratios from 2500 A/5 A through to 5000 A/5 A for this model.

The transformer has a rated operating voltage of AC 0.66 kV, rated frequency of 50 to 60 Hz and a rated secondary current of 5 A. The manufacturer specifies accuracy classes of 0.2, 0.5S and 0.2S for the series.

Its G-180x50II configuration has a 185 x 55 mm through-hole dimension, with an overall size of 240 x 181 x 60 mm according to the manufacturer's dimensional table.

How it works

• The primary conductor or busbar passes through the transformer opening.
• The AC current flowing through the primary creates a corresponding magnetic field in the transformer core.
• The transformer produces a proportional secondary current for connection to compatible meters or protection equipment.
• The secondary circuit can then be used for electrical measurement and monitoring.

Why choose this product

• Designed specifically for electrical metering applications.
• Supports high primary current ratios from 2500 A to 5000 A.
• Provides a 5 A secondary current for compatible measurement equipment.
• Large through-hole configuration accommodates suitable busbar arrangements.
• Flip-type construction provides convenient access to the secondary wiring.

Benefits

• Allows high AC currents to be measured using compatible lower-current instruments.
• Provides a practical method of current transformation in electrical distribution equipment.
• The transparent cover allows the secondary wiring arrangement to be viewed.
• Suitable for integration with compatible meters and current-based protection equipment.
