Procurement Notes
Verify the specific current rating (125 A or 137 A) required for your application against the datasheet specifications. Confirm that the voltage range of 305 to 760 VAC matches your system requirements. Ensure chassis mounting space accommodates the physical dimensions. Check for compliance with local safety regulations such as UL 60939-3 and IEC 60939-3 before finalizing procurement.
Selection Notes
Select this model when high-current three-phase filtering is needed for drive systems. The two-stage architecture provides superior attenuation compared to single-stage units. Verify that the terminal block interface suits your wiring infrastructure. Consider the physical footprint as it is designed for efficient panel space utilization in industrial enclosures.
Part Context
This component belongs to the Schaffner FN3287/FN3288 series, which are recognized as compact book-style filters for power electronics. The series is engineered specifically for demanding environments involving inverters and drives. It represents a specialized solution for managing electromagnetic interference in high-power three-phase applications.
Replacement Considerations
Cross-reference part numbers within the FN3287 series for alternative current ratings. Verify compatibility with existing mounting hardware and terminal configurations. Ensure substitute models maintain the same voltage and frequency specifications.
