Current Sense Transformers Procurement Notes

Verify the specific part number 855-305/075-201 against official WAGO documentation to confirm compatibility with existing system requirements. Ensure that the primary current rating of 75 A and secondary output of 5 A align with the connected measuring instruments. Check that the maximum burden of 2.5 VA is sufficient for the intended circuit load. Confirm mounting constraints and environmental conditions match the component's specifications before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when a non-invasive solution is required for monitoring currents up to 75 A in 50/60 Hz systems. The choice is appropriate for applications demanding high mechanical stability and resistance to vibration. Consider the CAGE CLAMP interface if rapid and tool-free wiring is necessary. Ensure the accuracy class 1 specification meets the precision requirements of the downstream measurement devices. Evaluate space constraints as the unit requires chassis mounting.

Current Sense Transformers Part Context

This model belongs to the WAGO 855 series of plug-in current transformers. The series is characterized by its modular design and robust construction suitable for industrial use. The 855-305/075-201 variant specifically addresses applications requiring a 75 A primary current rating.
