Procurement Notes
Verify the specific suffix (0,5) indicates the required accuracy class during procurement. Confirm that the 600 A primary rating matches the circuit requirements. Ensure the DIN rail mounting style is compatible with existing panel infrastructure. Check regional availability as distribution status may vary by location.
Selection Notes
Select this component when a 600 A primary current capacity is required for industrial monitoring. The 5 A secondary output is standard for connecting to ammeters or data acquisition systems. The 0.5 accuracy class suits general industrial measurement needs. Verify the 5 VA burden capability supports the connected instrument load.
Part Context
This part belongs to the CMA series of closed current transformers from Weidmüller. It is designed for industrial environments requiring reliable current sensing. The series offers various primary current ratings and accuracy classes to suit different measurement scales.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer catalogs for alternative models with matching 600 A primary ratings and DIN rail compatibility.
