FN3311-600-99-C16-R55

Overview

The Schaffner FN3311-600-99-C16-R55 is a three-phase busbar EMC filter designed for high-power industrial applications. It features a rated current of 600 A and supports voltages up to 520 VAC phase-to-phase and 300 VAC phase-to-neutral. The unit operates within a frequency range of 0 Hz to 60 Hz and utilizes a chassis mount configuration with busbar terminations. Key electrical specifications include a leakage current of 60 µA and an integrated common-mode (CY) capacitor. The device belongs to the FN3311 series, which is engineered for compact integration in demanding power environments.

Feature Summary

• Three-phase busbar input and output configuration for direct high-current connection
• Integrated common-mode capacitor for enhanced noise suppression
• Chassis mount design optimized for space-constrained industrial enclosures

Applications

• Industrial motor drive systems
• High-power renewable energy inverters
• Large-scale manufacturing equipment power supplies

Procurement Notes

Verify that the specific suffix codes match the required terminal type and mounting hardware. Confirm voltage ratings align with the target system's phase-to-phase and phase-to-neutral requirements. Ensure physical dimensions accommodate the designated chassis space. Cross-reference certification marks such as UL or CE against regional regulatory mandates before finalizing procurement orders.

Selection Notes

Select this component when a 600 A continuous current rating is required for three-phase filtering. The busbar termination style necessitates compatible busbar fabrication or adapter plates. Evaluate the 60 µA leakage current against safety grounding limits. Consider the chassis mount form factor if panel mounting is not feasible. Verify thermal management requirements based on the expected load profile and ambient temperature conditions.

Part Context

This model is part of the Schaffner FN3311 series, which specializes in compact, high-current three-phase EMC filtering solutions. The series is characterized by its ability to handle significant power loads while maintaining a small footprint. The FN3311-600 variant specifically addresses the needs of heavy-duty industrial applications requiring robust noise attenuation without excessive physical size.

Replacement Considerations

Direct replacements within the same series include models with different current ratings, such as the FN3311-400-99-C16-R55 or FN3311-250-99-C16-R55. Substitution requires verifying that the alternative current rating meets or exceeds the application's peak and continuous load demands. Terminal compatibility and physical mounting dimensions must also be confirmed.
