Current Sense Transformers Procurement Notes

Verify that the specific order code matches the required accuracy class and rated power specifications. Confirm compatibility with existing busbar dimensions and mounting hardware before procurement. Ensure the frequency range aligns with the target application's operational standards to maintain measurement integrity.

Current Sense Transformers Selection Notes

Select this component when a 200 A primary current rating and 5 A secondary output are required. Consider the 0.5 accuracy class for standard metering needs. Evaluate the pluggable form factor against fixed-mount alternatives based on maintenance accessibility requirements and spatial constraints within the enclosure.

Current Sense Transformers Part Context

This model belongs to the WAGO 855 Series of plug-in current transformers. The series provides standardized interfaces for industrial automation systems. The part number structure indicates specific primary current and secondary current configurations within the product family.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 200:5 ratio, 5 VA burden, and Class 0.5 accuracy. Verify physical dimensions and mounting style compatibility. Cross-reference with other 855 Series variants if exact part availability is limited.
