Current Sense Transformers Procurement Notes

Verify the specific part number suffix to ensure compatibility with existing interface modules. Confirm that the primary current rating of 200 A matches the circuit requirements. Check that the secondary output of 5 A aligns with connected metering or protection devices. Ensure the physical dimensions and mounting style fit the designated chassis space. Validate insulation class specifications against environmental conditions.

Current Sense Transformers Selection Notes

Select this component when a 200 A primary current capacity is required for accurate monitoring. The 5 VA burden capability suits standard secondary instrumentation. Consider the 26 mm feed-through diameter for cable sizing constraints. The 50 to 60 Hz frequency range covers standard utility power applications. Accuracy class 1 ensures sufficient precision for billing or control purposes.

Current Sense Transformers Part Context

This model belongs to the WAGO 855 Series of current transformers. These units are engineered for use in industrial automation and electrical infrastructure. The series offers various primary current ratings to suit different load profiles. The 855-305 variant specifically addresses high-current applications requiring robust isolation.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series models with identical 200 A primary ratings, such as the 855-305/250-501 if higher capacity is acceptable. Verify that any replacement maintains the same 5 A secondary output and 5 VA rating. Ensure mechanical compatibility with the existing chassis mount configuration.
