Now with new added features for more protection!
Portable whole-RV surge and spike protectors now offer more than twice the rated protection of earlier models. Easy to see LCD display uses plain, easy to understand language to keep you informed of status at a glance. Built-in intelligence lets these units reset automatically at power restoration. Each now shuts off power in the event of an open ground or thermal line/load overtemperature condition, as well as in the event of an open neutral, low (under 102 volts) and high (over 132 volts) voltage or reverse polarity to protect your RV and its electrical components from damage and fire. Continuously monitors for voltage and amp draw (RMS) and reverse polarity (miswired pedestal or elevated ground voltage). Built-in 128 second reset delay protects air conditioner compressors. Two-light LED backup indicators for power and faults. More compact design for easier storage. Easy pull handles on connectors for safety and convenience.

Shuts Off Power in Event of:

  • Open Neutral
  • Open Ground
  • Low (<102V) and High (>132V) Voltage
  • Thermal Line/Load Overtemperature


  • Voltage and Amp Draw (RMS)
  • Surge Failure (light indicates when surge protection has expired)
  • Reverse Polarity (miswired pedestal, elevated ground voltage)


  • 3850 Joules surge protection
  • 6500 amps spike protection
  • 120/240 volts, 50 amps
  • 6/4 cord

    Good thing I bought this surge guard for the RV. Noticed a voltage creep over the past couple of weeks. Now up to 132v and isolated the coach as it is designed to do. Called power company (APS) and after discussing the problem with them for almost an hour, convinced them that I didn't need an electrician I need APS to fix the problem before my electronics got fried in the house. They just left and confirmed the voltage was too high and the tech informed me they have had previous reports in the area.
    Pros: As expected, Easy installation, Peace of mind

    Worked good for 18 months. Failed and will not power motor home 6 months after warrantee expired. I confirmed that the power failure was from the Surge Guard and not the source of power by trying 3 known good power supplies.
