855-5105/1000-000

Current Sense Transformers Overview

The WAGO Corporation 855-5105/1000-000 is a split-core current transformer designed for non-invasive AC current measurement. It features a primary rated current of 1000 A and a secondary rated current of 5 A, operating within a frequency range of 50 Hz to 60 Hz. The device has a rated power of 0.5 VA and an accuracy class of 0.5. It utilizes wire leads with a cable length of 3 m for termination. This chassis-mount component allows for retrofitting existing electrical systems without interrupting ongoing processes, providing reliable data acquisition for energy monitoring applications.

Current Sense Transformers Feature Summary

• Non-invasive split-core design enables installation around existing conductors without circuit interruption
• High insulation voltage ratings support safe operation in demanding industrial environments
• Compact form factor facilitates space-saving integration into control panels or retrofitted systems

Current Sense Transformers Applications

• Retrofitting existing electrical distribution systems for energy data acquisition
• Monitoring AC current in industrial machinery and production lines
• Integration with energy management systems for real-time load analysis

Current Sense Transformers Procurement Notes

Verify that the required primary current does not exceed 1000 A and the system frequency matches the 50 Hz to 60 Hz specification. Confirm that the connected burden does not exceed the 0.5 VA rated power to maintain the stated 0.5 accuracy class. Ensure the 3 m wire lead length is sufficient for the intended connection to the measuring instrument. Check that the mounting environment accommodates the thermal range and insulation requirements specified by the manufacturer.

Current Sense Transformers Selection Notes

Select this model when a non-invasive solution is required for currents up to 1000 A at standard power frequencies. The split-core architecture is suitable for applications where permanent installation on busbars is impractical or impossible. Consider the 0.5 accuracy class for general metering purposes rather than high-precision laboratory measurements. Evaluate the 3 m cable length against the distance to the signal processing unit to avoid the need for signal-altering extensions.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series, which focuses on space-saving current measurement technologies. The series includes both Rogowski coils and split-core transformers designed for easy retrofitting. The 855-5105/1000-000 specifically addresses the need for robust, non-invasive current sensing in industrial settings, complementing other solutions like Rogowski coils that offer different accuracy classes and physical dimensions.

Current Sense Transformers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 1000 A primary rating, 5 A secondary output, and 0.5 VA burden capacity. Verify compatibility with the existing wiring configuration and mounting constraints.
