Overview
The FN3311IT-1000-99-C18-R5 is a three-phase busbar filter manufactured by Schaffner EMC Inc. It features an insulation technology (IT) design rated for 500VAC. The unit supports a current rating of 1000A and utilizes a chassis mount installation style with busbar termination. This component belongs to the FN3311 series, designed for high-power applications requiring robust electromagnetic interference suppression in industrial environments.
Feature Summary
- Insulation technology design suitable for IT power systems
- High current capacity for heavy-duty industrial loads
- Busbar termination for secure mechanical and electrical connections
Applications
- Industrial motor drives
- Power conversion systems
- Heavy machinery control panels
Procurement Notes
Verify the specific insulation technology requirement against the source power system configuration before procurement. Confirm that the 500VAC rating aligns with the operational voltage levels. Ensure the chassis mounting provisions match the enclosure design. Validate that the busbar termination type is compatible with the incoming and outgoing cable assemblies.
Selection Notes
Select this model when operating within insulated neutral or IT power networks where ground fault detection is critical. The 1000A rating dictates suitability for high-power distribution points. Consider the physical dimensions and thermal management requirements associated with busbar-mounted filters in enclosed spaces compared to standard terminal-based alternatives.
Part Context
This component is part of the FN3311 series from Schaffner, which specializes in compact three-phase EMC/EMI filters. The series is engineered for high-current applications, offering reliable noise suppression while maintaining low leakage currents. The IT variant specifically addresses the unique grounding constraints of isolated power systems common in marine and industrial sectors.
Replacement Considerations
Cross-reference with other FN3311 series variants if different voltage ratings are required. Verify compatibility with existing busbar geometries when substituting similar models from the same manufacturer family.
