ACREL 150 x 50II Current Transformer for Electrical Monitoring

The ACREL 150 x 50II Current Transformer for Electrical Monitoring is designed for current measurement in low-voltage electrical installations. The horizontal square-hole construction allows the primary conductor to pass through the transformer, making it suitable for applications involving busbars and multiple cables.

The 150 x 50II variant has a 155 x 55 mm through opening and a 210 x 176 x 55 mm overall size. Acrel's technical documentation lists current ratio configurations from 1000/5A through to 5000/5A for this size.

How it works

• The primary conductor or busbar passes through the transformer's central opening.
• Current flowing through the primary conductor produces a corresponding magnetic field in the transformer core.
• The current transformer provides a reduced secondary current for connection to compatible measuring instruments and monitoring equipment.
• The applicable current ratio and rated burden depend on the selected configuration.

Why choose this product

• Designed specifically for AC current measurement.
• The 155 x 55 mm through opening accommodates appropriately sized conductors or busbars.
• Available with several high-current ratios for different measurement requirements.
• Solid-core construction is suited to fixed electrical installations.
• Acrel provides dimensional, electrical and installation information for the AKH-0.66/II series.

Benefits

• Provides a practical method of reducing measured circuit current for compatible measurement equipment.
• Supports current monitoring in electrical distribution and power measurement systems.
• The defined physical dimensions assist with equipment selection and installation planning.
• The horizontal through-hole configuration allows the primary conductor to pass through the transformer without requiring the transformer to form part of the conductor itself.
