Overview
The FN3280H-300-99 is a three-phase WYE (4-wire + ground) EMC line filter from the Schaffner FN3280 series. It features a two-stage terminal post design with busbar input and output connections. Rated for 300 A current at 520 VAC, it operates within a frequency range of DC to 60 Hz. The unit utilizes chassis mount installation and exhibits a leakage current of 42.1 mA. It complies with UL, CSA, and IEC/EN standards.
Feature Summary
- Two-stage terminal post architecture for enhanced attenuation
- Busbar input and output configuration for high-current handling
- Touch-safe terminal block design ensuring operator safety
Applications
- Regenerative drive units
- High-power industrial motor drives
- Three-phase power conditioning systems
Procurement Notes
Verify the specific current rating suffix against the datasheet, as the model number indicates 300 A but some sources reference higher variants in the same series. Confirm that the busbar termination style matches the system's mechanical interface requirements. Ensure compliance with local electrical codes for chassis-mounted filters in industrial environments.
Selection Notes
Select this component when high current capacity and low leakage are required for three-phase applications. The busbar connection style necessitates compatible mounting hardware. Consider the physical dimensions and weight for structural support during installation. Verify voltage ratings align with the specific AC supply network.
Part Context
This filter belongs to the Schaffner FN3280 series, which combines high attenuation performance with low leakage current. The series is designed for robust industrial environments, offering touch-safe terminals and durable construction suitable for demanding power line filtering tasks in heavy machinery and energy systems.
Replacement Considerations
The part number alias 803419-SF may serve as an equivalent identifier. Verify pinout and dimensional compatibility before substituting with other models in the FN3280 family or competing high-current three-phase filters.
