Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required primary current rating of 150 A and secondary output of 5 A. Confirm compatibility with existing DIN rail standards and ensure the conductor feed-through diameter of 26 mm aligns with the cable specifications in the installation environment. Check for RoHS compliance if environmental regulations apply.

Current Sense Transformers Selection Notes

Select this model when a 150 A primary current capacity is needed with a 5 A secondary output. Ensure the application requires class 1 accuracy and operates at 50 or 60 Hz. Consider the physical dimensions and DIN rail mounting requirement during system design. Verify that the 5 VA burden capability meets the connected instrument requirements.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers, which are engineered for industrial interface modules. The series offers various primary current ratings to suit different load conditions while maintaining consistent plug-in functionality and DIN rail compatibility for standardized industrial installations.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series models with identical 150 A primary current and 5 A secondary current ratings, such as variants with different ordering suffixes if they maintain the same technical specifications. Cross-brand replacements must match the 150:5 ratio, 5 VA rating, and DIN rail form factor.
