FN3311IT-600-99-C18-R5

Overview

The FN3311IT-600-99-C18-R5 is a three-phase busbar filter from the Schaffner FN3311 series, designed for high-power industrial applications. It features an IT (isolated terra) configuration with a rated voltage of 500 VAC and a current rating of 600 A. The unit utilizes screw terminal connections for secure mounting and electrical interfacing. Certified to UL 1283 standards, it supports operation within a temperature range of -40°C to +100°C. The filter provides single-stage attenuation for electromagnetic interference suppression in power distribution systems.

Feature Summary

• Three-phase busbar architecture optimized for high-current industrial power lines
• IT isolated terra design ensuring operational continuity during ground faults
• Robust chassis mount construction with screw terminals for secure integration

Applications

• Industrial motor drive systems requiring EMC compliance
• Power distribution units in isolated grounding networks
• Heavy machinery power input stages

Procurement Notes

Verify the specific IT configuration requirement against system grounding topology before procurement. Confirm that the 600 A current rating aligns with peak load demands. Ensure chassis mounting dimensions accommodate the physical footprint. Check for updated certification marks such as UKCA if applicable to the target market. Validate terminal torque specifications during installation.

Selection Notes

Select this model when an isolated terra (IT) network is required rather than standard grounded systems. The 600 A rating suits heavy-duty industrial loads. Compare insertion loss characteristics against specific EMI noise profiles. Ensure the operating temperature range covers the environmental conditions. Verify compatibility with existing busbar geometries and terminal hardware.

Part Context

This component belongs to the FN3311 series of compact three-phase high-power filters by Schaffner. The series is engineered for demanding industrial environments where space efficiency and high current handling are critical. The IT variant specifically addresses safety and continuity requirements in isolated power systems common in medical and industrial sectors.

Replacement Considerations

Cross-reference part numbers within the FN3311 series for alternative current ratings or voltage levels. Verify mechanical compatibility with existing mounting structures. Ensure electrical parameters match the original design intent without compromising safety certifications.
