FN5420-1000-99-E0XXT

Overview

The FN5420-1000-99-E0XXT is a three-phase LC sine wave output filter manufactured by TE Connectivity / Schaffner. Designed for motor drive applications, this unit operates at a rated voltage of 500VAC and supports a current capacity of 1000A. It features an IP00 protection rating and weighs approximately 820 kg. The component functions as a dv/dt output reactor to mitigate overvoltage issues.

Feature Summary

• Eliminates overvoltage at motor terminals to ensure reliable operation
• Reduces motor noise and protects against electrical stress
• Designed for high-current industrial motor drive systems

Applications

• High-power variable frequency drive installations
• Industrial motor protection systems
• Applications requiring compliance with IEC 61800-3 EMC standards

Procurement Notes

Verify the specific ordering suffix and technical specifications directly with the manufacturer or authorized distributors before procurement. Confirm that the part number matches the required current and voltage ratings for your specific application. Factory special order status may apply; contact suppliers for current availability and lead time details.

Selection Notes

Select this component when driving large motors from standard PWM inverters to prevent insulation damage. Ensure the system voltage does not exceed 500VAC and the load current remains within the 1000A limit. Consider the significant physical weight and mounting requirements associated with this high-capacity filter unit.

Part Context

This model belongs to the FN5420 series of sine wave filters from Schaffner. These units are engineered to convert pulse-width modulated inverter outputs into near-sinusoidal waveforms. The series addresses common issues in long-cable motor drives, such as reflected waves and bearing currents.

Replacement Considerations
