Overview
The FN3311-1500-99-C16-R55 is a three-phase EMC/EMI power line filter from the Schaffner FN3311 series, rated for 1500 A and 500 kVA. It operates at 520 VAC phase-to-phase and 300 VAC phase-to-neutral within a 0 Hz to 60 Hz frequency range. The unit features busbar connections for both input and output terminals and utilizes chassis mounting. It includes integrated Y-capacitors and complies with UL 1283, CSA, and IEC/EN 60939 standards.
Feature Summary
- High-power three-phase filtering capability designed for industrial applications
- Busbar terminal configuration for robust electrical connections
- Integrated Y-capacitor design for enhanced noise suppression
- Chassis mount construction for secure installation
Applications
- Industrial motor drive systems
- Large-scale renewable energy inverters
- Heavy-duty welding equipment
- Industrial power conditioning units
Procurement Notes
Verify that the specific part number matches the required current rating of 1500 A and voltage specifications of 520 VAC. Confirm that the busbar connection type aligns with existing system infrastructure. Ensure compliance requirements such as UL 1283 and CSA are met for the intended deployment region before finalizing procurement.
Selection Notes
Select this component when high current handling capacity exceeding standard filters is necessary. The busbar interface requires compatible mating hardware for proper installation. Consider the physical dimensions and thermal management needs associated with high-power dissipation in enclosed environments during system design.
Part Context
This model belongs to the Schaffner FN3311 series, which specializes in compact, high-current three-phase filters. The series is engineered for demanding industrial environments where significant electromagnetic interference suppression is critical alongside high power throughput capabilities.
Replacement Considerations
Cross-reference with other FN3311 variants for different current ratings if 1500 A is not required. Verify mechanical compatibility with existing busbar layouts when substituting similar models.
