2511690000

Overview

The Weidmüller 2511690000 is a split-core current transformer designed for non-invasive measurement of alternating current. It features a primary rated current of 50 A and a secondary nominal output of 1 A. The device supports a maximum burden load of 1 VA and adheres to accuracy class 3 standards. With dimensions of 67.30 mm in length and 1.638 inches in width, it utilizes a free-hanging in-line mounting configuration. The unit operates within a temperature range of -25°C to 70°C and is suitable for 50 Hz frequency applications.

Feature Summary

• Split-core design enables installation without disconnecting the primary conductor
• Utilizes rms value methods for precise current consumption measurement
• Asymmetrical cable feed-through facilitates straightforward integration

Applications

• Measurement of current consumption in electrical loads
• Integration into monitoring systems requiring non-invasive sensing
• Industrial equipment current tracking

Procurement Notes

Verify that the required secondary current matches the 1 A specification and confirm the burden load does not exceed 1 VA. Ensure the primary circuit current remains within the 50 A rating. Check that the operating environment stays within the -25°C to 70°C range. Confirm compatibility with 50 Hz systems. Validate physical space constraints against the specified dimensions before ordering.

Selection Notes

Select this component when non-invasive current measurement is required for circuits up to 50 A. It is appropriate for applications where breaking the primary conductor is impractical. Consider the 1 A secondary output and 1 VA burden limit when designing the connected measurement circuitry. Ensure the accuracy class 3 meets the system requirements. Verify that the free-hanging mounting style fits the installation environment.

Part Context

This part belongs to the Weidmüller current transformer series, specifically engineered for commercialized industrial applications. The model KCMA-18-50-1A-1VA-3 HUT represents a standardized solution for current sensing. It is distinct from invasive ring-type transformers due to its split-core architecture. The product status is confirmed as commercialized, indicating availability for standard procurement channels.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching primary current ratings, secondary output specifications, and physical dimensions. Verify that any alternative component maintains the same accuracy class and burden capacity.
