Dicor 30 Amp Plug-In RV Surge Protector | Up to 1050 Joules, 125 VAC

This 30-amp plug-in surge protector sits between the campground pedestal and your shore power cord, protecting your RV's electrical system from surges, spikes, and voltage swings. If incoming voltage drops below or exceeds the safe range, it disconnects the circuit within milliseconds and automatically restores power once voltage stabilizes.

• Auto on/off protection against over- and under-voltage
• 3-mode surge protection: line-to-neutral, line-to-ground, neutral-to-ground
• 1050-joule total surge protection rating
• Response time under 1 nanosecond
• Easy-to-read diagnostic lights show system status
• Weather-resistant housing

A compact, plug-in way to add surge protection without hardwiring a unit into the RV.
