ACREL 40II Current Transformer for Electrical Monitoring
ACREL 40II Current Transformer for Electrical Monitoring is a horizontal square-hole current transformer designed for electrical current measurement. The 40II version accommodates a 40 x 10 mm busbar arrangement and supports multiple rated current ratios from 100/5A to 1000/5A. It is designed for use with electrical measuring instruments and can be installed in electrical equipment and distribution assemblies.
The ACREL 40II Current Transformer for Electrical Monitoring is part of Acrel's AKH-0.66/II series of measuring current transformers. It uses a horizontal square-hole configuration and is intended for applications where current needs to be measured through a busbar or cable without directly connecting the measuring instrument to the primary circuit.
The ACREL 40II Current Transformer for Electrical Monitoring model has a 40 x 10 mm busbar specification and provides a range of rated current ratios. Depending on the selected ratio, the manufacturer lists accuracy classes and corresponding rated loads suitable for electrical measurement applications.
How it works
- The primary conductor or busbar passes through the transformer's central aperture.
- The current transformer converts the primary current into a proportional secondary current.
- The secondary circuit can then be connected to compatible electrical measuring instruments or monitoring equipment.
- The 40II configuration is specified for one straight-through turn.
Why choose this product
- Designed specifically for electrical current measurement.
- Square through-hole construction accommodates the manufacturer's specified 40 x 10 mm busbar arrangement.
- Multiple current ratios are available within the 40II specification.
- Suitable for integration with compatible electrical measuring instruments and electrical assemblies.
- Compact dimensions make it suitable for applications where the available installation space is limited.
Benefits
The transformer provides an indirect method of measuring current, allowing compatible monitoring equipment to measure the electrical load without carrying the primary current directly through the measuring instrument.
The range of available current ratios also allows the transformer to be selected according to the electrical system being monitored.
