Overview

The Schaffner FN3311-2300-99-C28-R55 is a three-phase busbar EMC/EMI power line filter designed for high-current industrial applications. It features a Delta (3-wire + ground) configuration with chassis mounting and screw terminal connections. The unit operates at a rated voltage of 520 VAC phase-to-phase and 300 VAC phase-to-neutral, supporting a continuous current rating of 2300 A at 60 Hz. Certified under UL 1283, IEC/EN 60939, and CSA standards, it ensures compliance with international safety regulations.

Feature Summary

• High-capacity three-phase filtering for heavy-duty power systems
• Busbar input and output design for robust electrical connections
• Single-stage attenuation architecture for effective noise suppression

Applications

• Industrial motor drive systems
• Large-scale renewable energy inverters
• Heavy manufacturing power distribution units

Procurement Notes

Verify the specific current rating and physical dimensions against your system requirements before ordering. Confirm that the busbar interface matches your existing infrastructure. Check for updated certification marks such as UKCA if operating in relevant markets. Ensure proper thermal management is planned for high-current operation.

Selection Notes

Select this model when high current handling above 2000 A is required. The busbar configuration suits applications where standard terminals are insufficient. Consider the chassis mount style for integration into large enclosures. Verify voltage ratings align with the specific network configuration to ensure safe operation.
