Description
Filter Concepts 3E20-F 3X20A EMI Filter 3-Phase 250/440VAC 50/60Hz 20A
The Filter Concepts 3E20-F is a three-phase EMI/RFI line filter rated at 20 amps per phase (3×20A) and designed for use on 250/440VAC, 50/60Hz power systems. It suppresses conducted electromagnetic interference and radio-frequency interference on AC mains lines, protecting sensitive equipment downstream from noise generated by motors, drives, switching power supplies, and other industrial loads — and preventing noise from propagating back onto the mains. The unit is housed in a rugged steel chassis with a panel/chassis mounting foot and stud-style screw terminals.

Applications
Three-phase EMI line filters like the 3E20-F are standard components in industrial power distribution and machine control panels. They are installed at the AC input of variable-frequency drives (VFDs), servo drives, CNC machine tool controllers, industrial power supplies, and other switching equipment to meet conducted emissions limits under standards such as EN 55011/CISPR 11 and FCC Part 15. Filter Concepts is a U.S.-based manufacturer with a long history of supplying EMI/RFI suppression components to industrial OEMs and system integrators. The 250/440VAC dual-voltage rating makes this filter suitable for both North American 208–240VAC three-phase systems and international 380–440VAC three-phase systems, giving it broad applicability in manufacturing, process control, and automated test environments. Filters of this type remain in active everyday use anywhere power quality and EMC compliance are required.
This Filter Concepts 3E20-F 3-Phase EMI Line Filter has been inspected and is in good used condition. It was pulled from a working environment where it was in regular service. The metal enclosure shows surface oxidation and general shop wear consistent with industrial use — visible across the top and sides of the housing. The stud terminals (A, B, C, N) are intact and appear undamaged. The rating label on the bottom is legible and confirms model, voltage, and current ratings.
