855-5105/800-000

Current Sense Transformers Overview

The WAGO 855-5105/800-000 is a split-core current transformer designed for non-invasive electrical monitoring. It features a primary rated current of 800 A and a secondary rated current of 5 A. The device operates at frequencies between 50 Hz and 60 Hz with an accuracy class of 0.5. Rated power is specified at 0.5 VA. This chassis-mount component utilizes a split-core design to facilitate installation without circuit interruption.

Current Sense Transformers Feature Summary

• Non-invasive split-core construction allows for retrofitting existing systems without interrupting circuit operation.
• Chassis mount configuration provides secure physical installation for industrial applications.
• High primary current rating supports monitoring of heavy electrical loads.

Current Sense Transformers Applications

• Retrofitting existing electrical systems for current monitoring
• Industrial power distribution monitoring
• Electrical load measurement in control panels

Current Sense Transformers Procurement Notes

Verify the specific model suffix against official WAGO documentation to ensure compatibility with required primary current ratings. Confirm that the 800 A primary rating aligns with the target application's maximum load. Check termination style requirements, as this model typically utilizes wire leads. Ensure the operating frequency range matches the system's 50 Hz or 60 Hz supply. Validate accuracy class requirements against measurement precision needs before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when non-invasive current sensing is required for high-amperage circuits up to 800 A. The split-core design is optimal for installations where conductors cannot be disconnected. Consider the 0.5 accuracy class for standard industrial measurement tasks. Ensure the chassis mounting method fits the available enclosure space. Verify that the secondary output matches the input requirements of the connected measuring instrument or PLC module.

Current Sense Transformers Part Context

This part belongs to the WAGO 855 series of current transformers. The series includes variants with different primary current ratings, such as 1000 A models. These components are engineered for compact integration into electrical infrastructure. The split-core architecture distinguishes them from solid-core alternatives, offering flexibility for post-installation monitoring.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series split-core current transformers with matching 800 A primary ratings. Verify that alternative models maintain the same 5 A secondary output and 0.5 VA rated power. Ensure replacement units support identical chassis mounting and frequency ranges. Cross-reference datasheets to confirm terminal compatibility and accuracy specifications.
