The FN3288HV-20-33-C36-R65 is a three-phase EMC/RFI power line filter from the Schaffner FN3288 series. It features a slim design with a current rating of 20 A and operates at frequencies from DC to 60 Hz. The unit utilizes terminal block connections for both input and output, supporting Delta wiring configurations (3 wire + ground). Designed for chassis or flange mounting, it complies with UL 60939-3 and IEC 60939-3 standards.
Verify that the specific HV variant matches the system voltage requirements, as standard FN3288 models differ from high-voltage versions. Confirm terminal block compatibility with existing cabling infrastructure. Ensure mounting hardware supports the specified chassis or flange installation style. Check RoHS compliance status if required by project specifications.
Select this model when a two-stage filter is required for 20 A three-phase applications. The HV designation indicates suitability for higher voltage networks compared to standard variants. Terminal block termination is preferred over PCB mount for high-current industrial environments. Verify insulation and leakage current parameters against safety regulations.
This component belongs to the FN3288 family of power line filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series includes various current ratings and voltage options, such as standard and high-voltage (HV) versions. The FN3288HV specifically targets industrial applications requiring robust EMI performance in compact enclosures.
Direct substitutes include other FN3288HV series units with identical 20 A ratings and terminal block interfaces. Cross-reference with FN3288-20 variants only if voltage ratings are compatible. Verify physical dimensions and mounting hole patterns before substitution.
