Current Sense Transformers Procurement Notes

Verify that the specific order matches the exact model number 855-4101/250-001 to ensure correct primary current rating of 250 A and secondary output of 1 A. Confirm that the required accuracy class meets application standards, as this unit is classified as accuracy class 1. Check that the included 3-meter cable length satisfies the distance requirements between the transformer and the measurement device. Ensure the operating frequency range of 50Hz to 60Hz aligns with the local power grid specifications.

Current Sense Transformers Selection Notes

Select this component when non-intrusive installation on existing busbars or cables is required. The split-core architecture eliminates the need to interrupt the primary circuit during setup. Consider the physical dimensions and mounting style if space constraints exist within the enclosure. Verify that the load connected to the secondary side does not exceed the 0.2 VA rated power capacity to maintain measurement integrity.

Current Sense Transformers Part Context

This unit belongs to the WAGO 855 Series of current transformers, which are engineered for signal conditioning and current measurement applications. The series offers various primary current ratings, with this specific model providing a 250 A capacity. It serves as a critical interface between high-current primary circuits and low-current secondary measurement devices, ensuring accurate data transmission for monitoring and control purposes.

Current Sense Transformers Replacement Considerations

Direct substitutes include other models from the same series with identical electrical characteristics, such as the 855-4101/200-001, though primary current ratings differ. Ensure any replacement maintains the split-core configuration and compatible secondary output specifications.
