2680240000

Overview

The Weidmüller 2680240000 is a non-invasive solid core current sense transformer designed for DIN rail mounting. It features a primary current rating of 2000 A and a secondary rated current of 5 A. The device operates at a frequency of 50 Hz with an apparent power capacity of 10 VA on the secondary side. It maintains an accuracy class of 0.5 and includes an overcurrent limiting factor (FS) of 5. The physical dimensions are 120.00 mm in length and 2.047 inches in width.

Feature Summary

• Non-invasive solid core design for safe current monitoring without circuit interruption
• DIN rail mounting configuration for standardized industrial panel integration
• High primary current handling capability up to 2000 A for heavy load applications

Applications

• Industrial power distribution monitoring systems
• Electrical cabinet current sensing for automation control
• Energy metering infrastructure requiring high-current AC measurement

Procurement Notes

Verify the specific ordering suffix matches the required accuracy class and burden specifications. Confirm that the primary current rating aligns with the maximum expected load in the application. Ensure the mounting environment supports the DIN rail standard specified in the technical documentation. Cross-reference the secondary output requirements with connected instrumentation to guarantee compatibility with the 5 A rating.

Selection Notes

Select this component when high-current AC measurement is required in industrial settings. The solid core design eliminates the need for conductor threading, simplifying installation. Verify that the operating frequency matches the system's 50 Hz requirement. Consider the physical space constraints against the specified dimensions to ensure proper fit within the enclosure layout.

Part Context

This model belongs to the CMA-81 series of current transformers manufactured by Weidmüller. The series provides robust solutions for industrial current sensing applications. The part number 2680240000 specifically denotes the variant with 2000 A primary rating and 5 A secondary output. It is distinct from lower-rated models within the same product family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing busbar dimensions before considering alternative manufacturers. Ensure that any replacement meets the same accuracy class and thermal performance standards.
