855-3001/100-003

Current Sense Transformers Overview

The WAGO 855-3001/100-003 is a split-core current transformer designed for chassis mounting. It features a primary rated current of 100 A and a secondary rated current of 1 A, resulting in a current ratio of 100:1. The device operates within a frequency rating of 50 Hz to 60 Hz and has a rated power of 0.2 VA with an accuracy class of 3. It includes a 3 m cable length for connection purposes.

Current Sense Transformers Feature Summary

• Split-core design facilitates installation on existing busbars or cables without disconnecting the circuit.
• Chassis mount configuration allows for secure integration into control panels.
• Compact form factor supports retrofitting applications in electrical systems.

Current Sense Transformers Applications

• Retrofitting existing electrical distribution systems
• Current monitoring in industrial control panels
• Energy metering installations requiring non-intrusive measurement

Current Sense Transformers Procurement Notes

Verify the specific ordering number against official WAGO documentation to ensure correct specifications. Confirm that the required cable length and accuracy class meet project requirements. Check for any specific mounting hardware needs associated with the chassis mount style. Ensure compatibility with the connected measuring instrument's input range.

Current Sense Transformers Selection Notes

Select this component when a non-invasive current measurement solution is needed for circuits up to 100 A. The split-core architecture is essential for retrofits where opening the primary circuit is not feasible. Consider the 0.2 VA burden capability when determining the maximum load for the secondary circuit. Verify the 50/60 Hz frequency operation matches the system power supply.

Current Sense Transformers Part Context

This part belongs to the WAGO Compact split-core current transformer series. These transformers are engineered for signal conditioning and current sensing tasks. The series provides various primary current ratings to suit different load requirements while maintaining a consistent mechanical interface.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. When replacing, ensure the new component matches the 100:1 ratio, 1 A secondary output, and physical mounting dimensions. Verify that the accuracy class and rated power are sufficient for the application.
