855-1851/350-000

Current Sense Transformers Overview

The WAGO 855-1851/350-000 is a current and voltage tap designed for high-current applications up to 185 mm² conductors. It features a primary rated current of 350 A and a secondary rated current of 1 A, operating at 400 VAC. The device provides an accuracy class of 0.5 with a rated power of 0.2 VA. Classified as fused, it supports frequency ranges of 50Hz to 60Hz and utilizes chassis mounting for secure installation in energy data acquisition systems.

Current Sense Transformers Feature Summary

• Enables space-saving energy data acquisition without interrupting ongoing processes during retrofitting
• Eliminates saturation effects to maintain measurement accuracy across wide primary current ranges
• Achieves Class 1 measurement accuracy per EN 61869 standards through modern production methods

Current Sense Transformers Applications

• Retrofitting existing electrical systems for energy monitoring
• High-current circuit measurement in industrial machinery
• Power engineering infrastructure monitoring
• Control cabinet construction for energy data acquisition

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix matches the required primary current rating of 350 A and conductor size compatibility up to 185 mm². Confirm that the fused classification aligns with system protection requirements. Ensure the chassis mount configuration fits the designated enclosure space. Cross-reference the accuracy class 0.5 specification against metering precision needs before finalizing procurement orders.

Current Sense Transformers Selection Notes

Select this component when integrating current sensing into systems requiring direct connection to large cross-section conductors. The integrated voltage tap capability simplifies wiring compared to separate current transformers. Consider the 1 A secondary output standard for compatibility with common energy meters. Evaluate the chassis mount form factor against available panel space constraints in the target application environment.
