Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required primary current rating of 1000 A and secondary output of 1 A for your application. Confirm that the split-core mechanism accommodates the diameter of the conductor being measured. Ensure environmental conditions remain within the specified operating temperature range of -5°C to 50°C. Check for compliance with local safety standards and RoHS requirements before finalizing procurement.

Current Sense Transformers Selection Notes

Select this model when high primary current measurement up to 1000 A is required in a DIN rail environment. The split-core feature is critical for applications requiring installation on existing conductors without disconnection. Compare the 5 VA rated power against the burden of connected measuring devices to ensure accuracy. Consider the physical dimensions for adequate space in dense control panels.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series, which includes various current transformers and Rogowski coils. The series is characterized by space-saving designs and high resolution. Other models in the series offer different primary current ratings and accuracy classes, such as class 0.5 or 1, catering to diverse measurement precision needs in automation and power engineering.

Current Sense Transformers Replacement Considerations

Direct substitutes may include other WAGO 855 series split-core current transformers with identical 1000 A primary and 1 A secondary ratings. Verify compatibility regarding DIN rail mounting dimensions and insulation voltage levels. Cross-reference with similar industrial current transformers if WAGO availability is limited, ensuring matching electrical specifications.
