ACREL AKH-0.66 Z-3X Series Three Phase Combined Current Transformer

The ACREL AKH-0.66 Z-3X Series Three Phase Combined Current Transformer combines three current transformer channels into one compact assembly for three phase AC current measurement. It is designed for low voltage power distribution and can be paired with compatible monitoring and metering equipment.

The range includes Z-3xO10, Z-3xO15, Z-3xO20 and Z-3xO35 configurations. Depending on the selected model, the transformer provides different primary to secondary current ratios and accuracy classes.

How it works

• The three phase cables pass through the corresponding current transformer apertures.
• Each transformer detects the current flowing through its respective phase.
• The primary current is converted to the specified secondary signal for connection to compatible monitoring or metering equipment.
• The combined three phase construction reduces the number of separate transformer units required for three phase measurement.

Why choose this product

• Three phase measurement: Three current transformer channels are integrated into one assembly.
• Multiple aperture options: O10, O15, O20 and O35 versions are available for different cable sizes.
• Multiple current ratios: The available ratios cover applications from relatively low current measurement through to higher primary current monitoring.
• Compact installation: The combined construction can reduce installation space and secondary wiring requirements.
• Compatible monitoring equipment: Acrel identifies AMC16 and PZ300 as compatible applications.

Benefits

• Simplifies three phase current signal acquisition.
• Helps reduce wiring complexity in compact electrical panels.
• Provides selectable current ratios for different measurement requirements.
• Supports current monitoring in low voltage power distribution systems.
• Allows the transformer aperture to be selected according to the cable size.
