2656280000

Overview

The Weidmüller 2656280000 is a split-core residual current transformer (RCM) designed for industrial applications. It features a primary current rating of 18 A and supports round conductors with a diameter of 50.00 mm. The device operates within a frequency range of 30 Hz to 1 kHz and provides a secondary current rating of 40 mA. It utilizes DIN rail mounting for secure installation in electrical panels.

Feature Summary

• Split-core design allows for installation around existing conductors without disconnecting the circuit.
• Specifically engineered for residual current monitoring in industrial automation systems.
• Compatible with standard DIN rail mounting configurations for panel integration.

Applications

• Residual current monitoring in industrial control panels
• Safety systems requiring detection of earth leakage currents
• Automation equipment with AC current sensing requirements

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with your system's voltage and current specifications. Confirm that the 18 A primary rating and 50 mm conductor capacity meet your application needs. Check for any required accessories or mounting hardware specified in the technical datasheet before finalizing procurement orders.

Selection Notes

Select this component when residual current detection is required for circuits carrying up to 18 A. Ensure the cable diameter fits within the 50 mm opening. Consider the 30 Hz to 1 kHz frequency range for compatibility with your power supply characteristics. Verify DIN rail compatibility with your enclosure design.

Part Context
