855-5101/800-000

Current Sense Transformers Overview

The WAGO 855-5101/800-000 is a split-core current transformer designed for chassis mounting. It features a primary rated current of 800 A and a secondary rated current of 1 A. The device has a rated power of 0.5 VA and an accuracy class of 0.5. Operating within a frequency range of 50 Hz to 60 Hz, this component provides reliable current sensing capabilities for industrial applications requiring precise measurement integration.

Current Sense Transformers Feature Summary

• Split-core design facilitates easy installation without interrupting ongoing processes
• Chassis mount configuration ensures secure physical placement in control panels
• Compact form factor allows for space-saving energy data acquisition

Current Sense Transformers Applications

• Retrofitting existing electrical systems for energy monitoring
• Industrial process control current measurement
• Power distribution system monitoring

Current Sense Transformers Procurement Notes

Verify the specific part number suffix against official WAGO documentation to confirm exact specifications. Ensure compatibility with existing chassis mounting requirements and secondary circuit loads. Confirm that the 0.5 VA burden rating meets the connected instrument's requirements. Check for RoHS compliance status if required by project specifications. Validate the 800 A primary current rating matches the application's maximum load expectations.

Current Sense Transformers Selection Notes

Select this model when retrofitting is required without breaking primary conductors. Consider the 0.5 VA rated power to ensure the connected meter or relay does not exceed the transformer's capacity. Verify that the 800 A primary current aligns with the system's nominal operating range. The split-core architecture is essential for installations where cable removal is impractical or unsafe.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of Rogowski coils and current transformers. The series emphasizes high resolution and space savings while maintaining Class 1 measurement accuracy per EN 61869 standards. These devices are engineered for modern production methods that eliminate saturation effects across wide primary current ranges.

Current Sense Transformers Replacement Considerations

Consult official WAGO cross-reference lists for direct substitutes. Verify that any replacement maintains the 800 A primary rating, 1 A secondary output, and 0.5 VA burden capacity. Ensure mechanical dimensions and mounting style match the existing chassis setup.
