855-5101/500-000

Current Sense Transformers Overview

The WAGO 855-5101/500-000 is a split-core current transformer designed for amperage measurement. It features a primary rated current of 500 A and a secondary rated current of 1 A. The device operates with a rated power of 0.5 VA and maintains an accuracy class of 0.5. This component facilitates precise current sensing in electrical systems.

Current Sense Transformers Feature Summary

• Split-core design enables installation without interrupting the primary conductor.
• Provides accurate current measurement suitable for energy data acquisition.
• Supports retrofitting into existing electrical infrastructure.

Current Sense Transformers Applications

• Energy monitoring systems
• Electrical distribution panels
• Industrial process control

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the application load, as this specific model is rated for 500 A. Confirm compatibility with downstream instrumentation expecting a 1 A secondary output. Ensure the split-core mechanism accommodates the busbar or cable diameter present in the installation environment to guarantee secure closure and measurement integrity.

Current Sense Transformers Selection Notes

Select this model when a non-intrusive measurement solution is required for currents up to 500 A. The 0.5 accuracy class is appropriate for standard metering applications. Consider the physical dimensions of the split core relative to the available space around the conductor. Compare against other series if higher accuracy or different current ranges are necessary.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers. The series includes variants with different primary current ratings, such as the 855-5101/1000-000 for 1000 A applications. These devices are engineered for reliable performance in industrial and commercial electrical environments.

Current Sense Transformers Replacement Considerations

The 855-5101/1000-000 is a related variant within the same product family but is rated for 1000 A primary current. It is not a direct substitute for applications requiring 500 A unless the system can accommodate the higher rating. Verify technical specifications before considering any cross-model replacement.
