Overview
The Schaffner FN3288IT-20-33-C34-R60 is a three-phase EMC/RFI power line filter from the FN3288 series. It features a chassis mount design with terminal block termination. The unit is rated for 20 A current and 530 VAC voltage at 60 Hz operating frequency. Key electrical specifications include a maximum leakage current of 410 µA and compliance with UL 60939-3 and IEC 60939-3 standards. Physical dimensions are approximately 173 mm in length, 45 mm in width, and 132 mm in height, with an operating temperature range of -40 °C to +100 °C.
Feature Summary
- Provides effective electromagnetic interference suppression for three-phase power systems
- Utilizes a slim chassis mount form factor for compact integration
- Ensures safety compliance through certified leakage current limits
Applications
- Industrial machinery power input stages
- Medical equipment power supplies
- Information technology infrastructure hardware
Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to confirm exact termination style and mounting configuration. Confirm that the 20 A rating aligns with the system's continuous load requirements. Check for updated regulatory certifications relevant to the target market before finalizing procurement orders.
Selection Notes
Select this component when a three-phase solution with low leakage current is required for sensitive applications. Ensure the chassis mounting holes match the enclosure design. Verify that the terminal block connections accommodate the wire gauge used in the installation environment.
Part Context
This model belongs to the FN3288 series of three-phase filters designed for high-performance noise attenuation. The IT designation typically indicates specific internal circuitry or construction variations within the broader FN3288 family. These filters are engineered to meet stringent international EMC standards for industrial and commercial use.
Replacement Considerations
Consult official substitution guides for equivalent performance. Generic replacements may not match the specific leakage current or dimensional constraints.
