Overview
The FN3311-1000-99-C16-R55 is a three-phase busbar EMC/EMI line filter from the Schaffner FN3311 series. It features a rated current of 1000 A and operates at frequencies up to 60 Hz. The device supports AC voltage ratings of 520 V phase-to-phase and 300 V phase-to-neutral. Designed for chassis mounting, it utilizes busbar termination for robust electrical connections. The unit has a leakage current of 60 µA and functions within a temperature range of -40°C to 100°C.
Feature Summary
- High-current capacity designed for demanding industrial power applications
- Robust chassis-mount construction with busbar termination for secure installation
- Single-stage filtering configuration for effective EMI suppression
Applications
- Industrial motor drive systems
- Large-scale renewable energy inverters
- Heavy-duty manufacturing equipment power supplies
Procurement Notes
Verify that the specific part number matches the required 1000 A current rating and 520 VAC voltage specification before procurement. Confirm that the busbar termination style aligns with existing panel infrastructure. Ensure the chassis mount footprint accommodates the physical dimensions of the unit. Check for updated certification marks such as UKCA if operating in relevant jurisdictions.
Selection Notes
Select this component when high continuous current handling is required alongside significant noise attenuation. The busbar interface is suitable for low-inductance connections in high-power circuits. Consider the thermal environment, as the unit operates up to 100°C. Evaluate space constraints against the chassis mount requirements to ensure proper airflow and mechanical stability during operation.
Part Context
This model belongs to the FN3311 series of compact three-phase high-power filters manufactured by Schaffner. The series is engineered for applications requiring substantial current capacity and reliable electromagnetic interference reduction. These filters are typically integrated into power distribution systems where stringent compliance with emission standards is necessary.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the FN3311 family or other Schaffner series offering similar current and voltage ratings. Verify that any substitute maintains the busbar termination style and chassis mount form factor to ensure mechanical compatibility.
