FN3025HP-20-71

Overview

The Schaffner FN3025HP-20-71 is a three-phase EMC/RFI power line filter designed for DIN-rail or chassis mounting. It features a single-stage configuration with ring terminal inputs and outputs, supporting a rated AC voltage of 520 VAC and a continuous current of 20 A. The unit operates without a neutral connection in a Delta (3-wire + ground) arrangement. Constructed with a plastic housing and metal grounding plate, it provides effective electromagnetic interference suppression for industrial applications.

Feature Summary

• Single-stage filtering architecture for efficient EMI/RFI attenuation
• Integrated metal grounding plate combined with plastic enclosure for robust EMC performance
• Dual installation versatility allowing DIN-rail or chassis mounting configurations

Applications

• Motor drive systems
• Industrial equipment requiring electromagnetic compatibility
• Commercial machinery with three-phase power requirements

Procurement Notes

Verify the specific suffix code to confirm terminal type and mounting style. Ensure the input voltage rating matches the system's operational parameters. Confirm that the 20 A current capacity aligns with the load requirements. Check for RoHS compliance status if required by project specifications. Validate the absence of a neutral connection against the circuit design.

Selection Notes

Select this model when a three-phase filter is needed for motor drives or industrial loads up to 20 A. The HP series indicates a specific performance grade within the FN3025 family. Consider the physical mounting constraints as the unit supports both DIN-rail and chassis options. Ensure the 520 VAC rating exceeds the maximum line voltage to maintain safety margins.
