Current Sense Transformers Procurement Notes

Verify the specific part number 855-305/100-201 against official WAGO documentation to ensure correct specifications. Confirm that the required primary current is exactly 100 A and the secondary output matches 5 A. Check for compliance with local safety standards and voltage ratings of 690 V before procurement.

Current Sense Transformers Selection Notes

Select this component when a pluggable current transformer with a 100:5 ratio is required for high-current applications. Ensure the installation environment supports chassis mounting and that the system voltage does not exceed 690 V. Verify compatibility with existing interface electronics in the PG 29 series or similar WAGO modules.

Current Sense Transformers Part Context

This model belongs to the WAGO Series 855, which focuses on plug-on current transformers for interface electronic applications. It is categorized under current sense transformers and is distinct from other variants in the series by its specific 100 A primary rating and 2.5 VA burden capacity.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series models with identical 100:5 ratios, such as the 855-305/100-209, if pinout and mechanical dimensions are compatible. Cross-referencing datasheets is essential to confirm equivalent accuracy classes and rated powers.
