- Electrical equipment requiring EMI/RFI filtering
- Machinery operating at 480 VAC
Procurement Notes
Verify the exact part number DE20-4FF against official Tri-Mag or Curtis Industries documentation to confirm specifications such as voltage ratings and current capacity. Ensure compatibility with your system's frequency range of 47-63 Hz and three-phase configuration before procurement.
Selection Notes
Select this component when a three-phase filter is required for 20 amp circuits at 480 VAC. Consider its high-potential insulation ratings and low leakage current characteristics for sensitive industrial environments. Confirm physical mounting requirements and terminal types match the installation design.
Part Context
Tri-Mag, LLC, now a subsidiary of Curtis Industries, manufactures power components including EMI/RFI filters. The DE20-4FF belongs to their industrial filter lineup designed for business and industrial applications, focusing on reliable power quality management in three-phase systems.
Replacement Considerations
Consult official Tri-Mag or Curtis Industries cross-reference lists for verified substitutes. Ensure any replacement matches the 20A rating, 480VAC specification, and three-phase topology without altering functional performance.
