2753280000

Overview

The Weidmüller 2753280000 is a current sense transformer designed for industrial applications. It features a primary current rating of 800 A and a secondary current rating of 5 A. The device operates at 50 Hz with a power rating of 2.5 VA. It utilizes a free hanging mounting style, also described as in-line installation. This component serves as a passive sensing element for high-current monitoring within electrical systems.

Feature Summary

• Provides electrical isolation between primary high-current circuits and secondary low-current sensing circuits
• Designed for free-hanging or in-line installation to accommodate direct conductor passage
• Engineered for continuous operation at standard industrial frequencies

Applications

• High-current circuit monitoring in industrial automation panels
• Energy metering systems requiring galvanic isolation
• Protective relay input conditioning for large load currents

Procurement Notes

Verify the specific datasheet version for the 2753280000 part number before procurement. Confirm that the 800 A primary rating aligns with your system's maximum expected load. Ensure the 5 A secondary output matches the input requirements of your downstream measurement or control devices. Check for any specific mounting hardware requirements associated with the free-hanging configuration.

Selection Notes

Select this component when a robust, non-contact current sensing solution is required for currents up to 800 A. The 5 A secondary output is suitable for driving standard ammeters or current transformers with lower input ratings. Consider the physical space available for free-hanging installation versus enclosed mounting options. Evaluate the thermal performance under continuous full-load conditions to ensure long-term reliability.

Part Context

This current transformer belongs to Weidmüller's industrial sensor and connectivity portfolio. It complements their range of relay modules and terminal blocks by providing essential feedback data for system monitoring. The product supports the company's focus on reliable, durable components for control cabinet infrastructure and automation technology.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When replacing this unit, ensure the new component matches the 800 A primary rating, 5 A secondary output, and 50 Hz frequency specification. Verify mechanical compatibility with existing mounting structures.
