2753090000

Overview

The Weidmüller 2753090000 is a split-core current transformer designed for precise measurement of load current consumption using RMS value methods. It features a primary current rating of 400 A and a maximum secondary current of 1 A. The device supports a load capacity of 2.5 VA and adheres to tolerance class 1 accuracy standards. With a free-hanging mounting style, it accommodates asymmetrical cable feed-through. The unit measures 79.5 mm in height and operates at 50 Hz frequency, providing reliable current sensing capabilities for industrial applications requiring high-accuracy design.

Feature Summary

• Split-core design enabling installation without disconnecting the primary conductor
• Precise RMS value measurement for accurate current consumption monitoring
• Asymmetrical cable feed-through capability for flexible wiring configurations

Applications

• Industrial current monitoring systems
• Energy management and power distribution networks
• Load measurement in electrical infrastructure

Procurement Notes

Verify the specific order number 2753090000 against manufacturer documentation to ensure compatibility with existing system requirements. Confirm that the 400 A primary current rating and 1 A secondary output align with your sensor input specifications. Check for any required accessories or mounting hardware not included in the standard package. Ensure environmental conditions match the operational limits defined in the official datasheet.

Selection Notes

Select this component when a non-intrusive current measurement solution is required for circuits carrying up to 400 A. The split-core architecture allows for retrofitting into existing installations without power interruption. Consider the 2.5 VA burden limit when designing the secondary circuit to maintain the specified tolerance class 1 accuracy. Verify physical space constraints against the 79.5 mm height dimension.
