Procurement Notes
Verify the specific datasheet version for the 3-138-309 to confirm exact attenuation curves and leakage current specifications required for your EMC compliance strategy. Ensure that the mechanical dimensions and mounting hole patterns align with your enclosure design before finalizing procurement. Cross-reference the terminal torque specifications during assembly to maintain electrical integrity.
Selection Notes
Select this component when first-stage filtering is sufficient for the application's noise profile. Compare against higher-stage models if stricter emission limits are mandated. Evaluate the physical footprint constraints against the module's dimensions. Confirm that the 50 A current rating accommodates peak load requirements without derating issues in the expected operating environment.
Part Context
This part belongs to Schurter's FMAD NEO series, which focuses on compact power line filters for industrial environments. The series emphasizes ease of installation and high reliability. The 3-138-309 represents a specific configuration within this lineup, tailored for 50 A three-phase applications requiring standardized screw-mount interfaces.
Replacement Considerations
Consult official Schurter documentation for direct cross-references. Verify compatibility with existing mounting hardware and terminal block spacing when substituting.
