855-5001/500-000

Current Sense Transformers Overview

The WAGO 855-5001/500-000 is a split-core current transformer designed for non-intrusive electrical current measurement. It features a primary rated current of 500 A and a secondary rated current of 1 A, ensuring accurate signal transmission for monitoring systems. The device operates at a rated power of 0.5 VA with an accuracy class of 1, suitable for standard industrial applications. Designed for chassis mounting, it supports frequencies between 50 Hz and 60 Hz, allowing for easy installation around existing conductors without circuit interruption.

Current Sense Transformers Feature Summary

• Split-core design enables installation around existing busbars or cables without disconnecting the power line.
• Provides galvanic isolation between the high-current primary circuit and the low-voltage secondary measurement circuit.
• Chassis mount configuration ensures secure positioning within control panels or distribution boards.

Current Sense Transformers Applications

• Industrial energy monitoring and metering systems
• Electrical protection relay circuits requiring current feedback
• Power distribution panel instrumentation

Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required primary current rating of 500 A and secondary output of 1 A. Confirm that the accuracy class 1 meets the precision requirements of your measurement application. Ensure the chassis mounting style is compatible with your panel layout. Check for RoHS compliance if environmental regulations apply to your project specifications.

Current Sense Transformers Selection Notes

Select this model when non-invasive current sensing is required for high-amperage circuits up to 500 A. The split-core architecture is ideal for retrofitting existing installations where cable removal is impractical. Consider the 0.5 VA burden capability to ensure compatibility with downstream meters or relays. Verify frequency range compatibility with the system operating at 50 Hz or 60 Hz.
