2603440000

Overview

The Weidmüller 2603440000 is a CMA-RCM-DACT-60 residual current transformer designed for precise load current consumption measurement using RMS value methods. It features a closed current transformer design with a primary current rating of 25 A and supports round conductors up to 60.00 mm in diameter. The device provides asymmetrical cable feed-through capability and carries an IP40 degree of protection rating, ensuring reliable operation in industrial environments.

Feature Summary

• Enables precise measurement of load current consumption through RMS value calculation methods
• Utilizes a closed current transformer architecture for secure installation around conductors
• Accommodates round conductors with diameters up to 60.00 mm for flexible wiring configurations

Applications

• Industrial current monitoring systems requiring accurate RMS measurement
• Electrical installations utilizing asymmetrical cable feed-through arrangements
• Residual current detection circuits within DIN rail mounted control panels

Procurement Notes

Verify the specific model designation CMA-RCM-DACT-60 against project requirements to ensure compatibility with existing conductor sizes and primary current ratings. Confirm that the IP40 protection level meets the environmental conditions of the intended installation site. Cross-reference the 25 A primary current specification with system load data to prevent saturation or measurement inaccuracies during peak operation periods.

Selection Notes

Select this component when a closed-loop residual current transformer is required for measuring currents up to 25 A. Ensure the available space accommodates the 60.00 mm conductor opening diameter. This unit is suitable for applications demanding high precision via RMS methodology rather than simple peak detection. Verify that the mounting environment allows for the specified IP40 protection level without additional enclosure requirements.
