The Surge Guard 35550 Permanent RV Surge Protector monitors shore power continuously and shuts off when it detects excessive voltage or open neutral conditions that could damage electronic equipment in your coach, such as AC motors, TVs, stereos and more.

3 Mode Surge Protection protects the RV's sensitive electronic systems and appliances from potentially damaging power surge events without power interruptions to the RV.
Unit is permanently installed in the storage bay of your coach, preventing potential theft and damage from the elements.
Automatic reset on power restoration..
Multi-mode surge suppression.
Automatically shuts off the power when the following is present:
- Open ground.
- Open neutral.
- Low (<102V) and High (>132V) Voltage.
- Reverse polarity.
- Miswired pedestal.
- High neutral current.
Caution indicator lights indicate:
- Elevated ground voltage.
- Surge failure indication.
What each LED means on the unit:
- Input Power Indication - The green LED indicates power to RV when illuminated.
- Caution when Flashing/Time Delay and Fault Indicator - When unit is plugged in, the red caution LED is flashing indicating delay of 128 seconds. (This allows head pressure to bleed off the A/C compressor). Flashing can indicate faults are present, like possible mis-wiring or current to ground conditions (will prevent power reset).
- L1 Voltage - When green light is on L1 is between 102VAC to 132VAC. When the light is red, L1 is greater than 132VAC or below 102VAC, and power is shut off to protect your coach.
- L2 Voltage - When green light is on L2 is between 102VAC to 132VAC. When the light is red, L2 is greater than 132VAC or below 102VAC, and power is shut off to protect your coach.
- Surge Failure - If the red “SURGE” indicator LED is on, it means that the built-in surge protection has been sacrificed to protect your equipment and is no longer functioning properly. Other features will still function, but the unit is recommended to be replaced.
