  • SurgeX SX20NE/RT Surge Eliminator and Power Conditioner NEMA Enclosure with EMI/RFI Filtering and ICE

    The unit features both common mode and normal mode Impedance Tolerant EMI/RFI filtering as well as SurgeX ICE -Inrush Current Elimination for a comprehensive power conditioning solution.

    The SurgeX SX20NE/RT provides guaranteed surge protection and power conditioning for audio, video, broadcast and computer equipment.


    • Magnetic shielding steel enclosure
    • Advanced Series Mode surge protection
    • Advanced Impedance Tolerant EMI/RFI filtering
    • Self-test circuit with visual indicator
    • 10-year warranty
    • Made in U.S.A.

    SX20 NE/RT units are 20-amp load-capable, 12" x 12" x 4" NEMA enclosures and meet code for use at the service entrance, sub-panels and in ceiling plenums.

    SurgeX Advanced Series Mode technology is superior to conventional MOV circuitry or MOV-Hybrid designs and is completely non-sacrificial. Our zero let-through technology provides the most reliable protection available. It stops all surges up to 6,000 volts (unlimited surge current) without producing harmful side effects such as ground contamination or common-mode disturbances.
