Procurement Notes

Verify the specific order code CMA-31-300-5A-5VA-0,5 against the manufacturer's official documentation to ensure compatibility with existing infrastructure. Confirm that the required accuracy class and burden specifications align with the target application requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 300 A primary current rating and 5 A secondary output are required for industrial monitoring. Ensure the installation environment remains within the specified -5 °C to +50 °C operating temperature range. Verify that the DIN rail mounting style fits the available panel space and structural constraints.

Part Context

This part belongs to the CMA series of current transformers from Weidmüller. These devices are specialized for industrial environments where reliable current sensing is critical. The model number indicates specific electrical characteristics including primary/secondary ratios and accuracy classes.

Replacement Considerations

Check for direct substitutes with identical 300 A primary and 5 A secondary ratings. Ensure any replacement maintains the 5 VA burden capacity and 0.5 accuracy class. Verify physical compatibility with the existing DIN rail mounting configuration.
