The Schaffner FN3287-230-40-C26-R65 is a three-phase (Delta) EMC/RFI power line filter designed for inverter and power drive systems. It features a slim book-style chassis mount configuration with terminal block termination. The unit supports a rated current of 230 A at a voltage rating of 400 VAC, operating within a frequency range of 0 Hz to 60 Hz. Key electrical specifications include a leakage current of 5.9 mA and compliance with UL 60939-3 and IEC 60939-3 standards.
Verify the specific suffix codes against official TE Connectivity/Schaffner documentation to ensure correct termination style and mounting hardware compatibility. Confirm that the 230 A current rating aligns with the system's continuous load requirements and that the 400 VAC rating matches the network voltage. Check for required certifications such as UL or CE based on regional deployment regulations.
Select this model when high current capacity is required in a space-constrained environment. The slim profile distinguishes it from bulkier standard filters. Ensure the application utilizes a Delta configuration and requires terminal block connections rather than cable lugs. Validate thermal management needs given the high current handling capability.
This component belongs to the FN3287 series, which is engineered specifically for demanding industrial environments. The series emphasizes minimal footprint while maintaining high attenuation performance. It serves as a critical interface between the power source and sensitive drive electronics to prevent electromagnetic interference propagation.
Cross-reference part numbers such as FN3287-230-40-C33-R65 if different terminal block variants are needed. Verify physical dimensions and mounting hole patterns before substituting with other series models to ensure mechanical fit.
