855-5005/800-000

Current Sense Transformers Overview

The WAGO 855-5005/800-000 is a split-core current transformer designed for electrical measurement applications. It features a primary rated current of 800 A and a secondary rated current of 5 A. The device has a rated power of 0.5 VA and an accuracy class of 0.5. It operates within a frequency range of 50 Hz to 60 Hz. The unit supports chassis mounting and complies with RoHS standards, ensuring environmental safety.

Current Sense Transformers Feature Summary

• Split-core design facilitates installation around existing conductors without circuit interruption
• High precision measurement capability defined by accuracy class 0.5
• Chassis mounting configuration provides secure mechanical stability in control panels

Current Sense Transformers Applications

• Electrical energy metering systems requiring precise current monitoring
• Industrial automation control panels for load management
• Power distribution units needing isolated secondary current signals

Current Sense Transformers Procurement Notes

Verify the specific part number against official WAGO documentation to ensure compatibility with existing panel layouts. Confirm that the required secondary current rating of 5 A matches the input specifications of the connected measuring instruments or relays. Check for any regional certification requirements beyond standard RoHS compliance before finalizing procurement orders.

Current Sense Transformers Selection Notes

Select this model when high accuracy is required for primary currents up to 800 A. The split-core architecture is essential for retrofitting or installing transformers on live cables where disconnection is not feasible. Ensure the connected burden does not exceed the 0.5 VA rated power to maintain the specified accuracy class under operational conditions.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers, which are engineered for industrial electrical measurement tasks. The series offers various primary current ratings to suit different load profiles. The 855-5005/800-000 variant specifically addresses applications involving high-current circuits requiring reliable isolation and accurate signal transformation for downstream instrumentation.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series models with matching electrical characteristics, such as the 855-5005/600-000 or 855-5005/750-000, provided the primary current rating aligns with the application needs. Cross-manufacturer replacements must match the 800 A primary, 5 A secondary, and 0.5 VA burden specifications.
