2420910000

Overview

The Weidmüller 2420910000 is a closed current transformer designed for precise measurement of load current consumption using RMS value methods. It features a primary current rating of 500 A and a secondary maximum current of 5 A. The device supports a load capacity of 5 VA with an accuracy class of 1. It utilizes asymmetrical cable feed-through and includes a copper rail, but does not support snap-on mounting.

Feature Summary

• Closed design for precise RMS-based current measurement
• Asymmetrical cable feed-through configuration
• Includes integrated copper rail

Applications

• Measurement of current consumption in connected loads
• Industrial monitoring systems requiring high accuracy
• Electrical distribution panels

Procurement Notes

Verify the specific order code 2420910000 against manufacturer documentation to ensure compatibility with existing copper rail infrastructure. Confirm that the required accuracy class 1 meets project specifications. Check lead times as availability may vary by region. Ensure the operating temperature range of -5 C to +50 C aligns with the installation environment.

Selection Notes

Select this component when a closed current transformer with 500 A primary rating is required. The 5 A secondary output and 5 VA load capacity must match downstream instrumentation inputs. Verify the absence of snap-on mount requirement, as this model lacks that feature. Ensure the physical dimensions fit the designated DIN rail space.
