2420900000

Overview

The Weidmüller 2420900000, model CMA-31-600-5A-5VA-1, is a closed current transformer designed for precise measurement of load current consumption using RMS value methods. It features an asymmetrical cable feed-through and supports a primary current rating of 600 A with a secondary current rating of 5 A. The device has a maximum burden of 5 VA and a tolerance class of 1. It is intended for DIN rail mounting in industrial electrical applications.

Feature Summary

• Closed design for precise RMS-based current measurement
• Asymmetrical cable feed-through configuration
• DIN rail mounting style for industrial integration

Applications

• Industrial electrical system monitoring
• Load current consumption measurement
• Power distribution panel instrumentation

Procurement Notes

Verify the specific manufacturer designation, as documentation may list MBS AG or Weidmüller. Confirm the exact model suffix CMA-31-600-5A-5VA-1 matches your technical requirements. Ensure compatibility with existing DIN rail infrastructure and verify that the 600 A primary rating suits the target circuit load without exceeding thermal limits.

Selection Notes

Select this component when a closed-loop current transformer with a 600 A primary rating and 5 A secondary output is required. The 5 VA burden capacity must align with connected metering devices. The asymmetrical feed-through design dictates specific cable installation constraints compared to symmetrical alternatives.

Part Context

This part belongs to the CMA series of current transformers, specifically engineered for industrial environments. It serves as a sensing element for energy monitoring and protection systems. The 600 A rating places it in the high-current measurement category, suitable for main feeder circuits rather than branch circuits.

Replacement Considerations
