ACREL 80 x 50II Current Transformer for Electrical Monitoring
ACREL 80 x 50II Current Transformer for Electrical Monitoring is a low-voltage AC measurement current transformer with an 82 x 52 mm through opening for busbars or multiple cables. It is available with primary current ratios from 200 A to 3000 A and provides a 5 A or 1 A secondary output for compatible measuring instruments and energy meters.
The ACREL 80 x 50II Current Transformer for Electrical Monitoring is designed to convert higher primary AC currents into a lower secondary current suitable for electrical measuring equipment. The transformer can be installed around a suitable busbar or cable without requiring the measured conductor to be connected directly to the measuring instrument.
The 80 x 50II version has an 82 x 52 mm through opening, with a 120 x 141 x 45 mm outline size. Acrel lists primary current ratios from 200-250 A up to 2500-3000 A, with secondary ratios of 5 A or 1 A depending on the selected configuration.
How it works
- The primary conductor passes through the current transformer's central opening.
- Current flowing through the primary conductor creates a magnetic field in the transformer core.
- The transformer produces a proportional secondary current, typically 5 A or 1 A according to the selected ratio.
- The secondary circuit can be connected to compatible electrical measuring equipment or an energy meter.
Why choose this product
- Multiple current ratios: The 80 x 50II configuration is available for primary currents from 200 A through to 3000 A, depending on the selected ratio.
- Large through opening: The 82 x 52 mm opening is suitable for the specified busbar or cable arrangements.
- Measurement-oriented design: The transformer is intended for AC electrical measurement and use with measuring instruments.
- Flexible secondary output: Available configurations use a 5 A or 1 A secondary current.
- Practical installation: Acrel specifies mounting arrangements for the series, including straight-plate and pressure-plate fixing methods.
Benefits
- Provides an interface between higher-current electrical circuits and compatible measuring equipment.
- Allows current measurement without directly connecting the measuring instrument to the primary current.
- Suitable for electrical distribution and monitoring installations where a larger through aperture is required.
- The range of current ratios makes it possible to select a configuration appropriate to the measured circuit.
