Procurement Notes

Verify the specific phase configuration compatibility before integration, as this model is designated for three-phase delta systems. Confirm that the required current rating of 50 A aligns with the circuit design parameters. Ensure the chassis mounting method matches the enclosure specifications. Check for any regional shipping restrictions or availability limitations associated with this specific manufacturer part number prior to finalizing procurement plans.

Selection Notes

Select this component when a single-stage filter solution is sufficient for three-phase delta applications. It is appropriate for circuits requiring a 50 A continuous current capacity. Consider the physical dimensions and chassis mounting requirements during the mechanical design phase. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +100°C range for reliable long-term performance.
