A82-20100

Current Sense Transformers Overview

The Carlo Gavazzi A82-20100 is a single-phase industrial current transformer designed for non-invasive AC current measurement. It features a solid core construction with wire lead termination and panel mounting style. The device supports a primary current rating of 100 A and delivers a 4-20 mA DC analog output. It operates within a frequency range of 40 Hz to 1 kHz and functions at temperatures between -20 °C and +50 °C. Physical dimensions include a height of 20 mm, length of 95 mm, and width of 67.5 mm, with an approximate weight of 567 g.

Current Sense Transformers Feature Summary

• Provides true RMS AC current measurement via a 4-20 mA loop-powered analog output signal.
• Utilizes a solid core design for non-invasive installation on conductors.
• Supports operation across a wide frequency spectrum from 40 Hz to 1 kHz.

Current Sense Transformers Applications

• Industrial power monitoring systems requiring accurate current data acquisition.
• Building management systems for energy consumption tracking.
• Automation control panels for real-time load monitoring.

Current Sense Transformers Procurement Notes

Verify that the application requires a 100 A primary current rating and a 4-20 mA output signal compatible with the receiving controller's input impedance. Confirm that the operating environment temperature remains within the specified -20 °C to +50 °C range. Ensure the mounting location allows for the required panel cutout and physical clearance for the 95 mm length and 67.5 mm width. Check that the conductor size fits within the solid core aperture without obstruction.

Current Sense Transformers Selection Notes

Select this model when a robust, non-invasive solution for high-current AC measurement is needed. The 100 A rating suits heavy industrial loads, while the 4-20 mA output ensures noise immunity over long cable runs compared to voltage signals. Consider the panel mount requirement and verify that the 40 Hz to 1 kHz frequency range covers the system's operational bandwidth. This component is suitable where loop-powered simplicity reduces wiring complexity.

Current Sense Transformers Part Context

The A82-20100 belongs to Carlo Gavazzi's A82 series of industrial current transformers. This series focuses on providing reliable current sensing for automation and power distribution applications. The unit is manufactured by Carlo Gavazzi Inc., a provider of industrial automation components. It is distinct from other series such as the ICS or CA lines which serve different sensor categories like proximity or capacitive detection.

Current Sense Transformers Replacement Considerations

Cross-reference part number A82-2050 if a 50 A primary current rating is sufficient for the application, as it shares similar form factor and output specifications. Verify compatibility with existing panel cutouts and wiring configurations before substitution.
