Dicor 30 Amp Pigtail RV Surge Protector | Up to 4200 Joules, 3-Mode Protection

Plugged in between your shore power cord and the campground pedestal, this Dicor surge protector is built to catch the voltage spikes and surges that can otherwise damage your RV's electrical system. It provides up to 4200 joules of surge suppression across three modes: line-to-neutral, line-to-ground, and neutral-to-ground.

An automatic cutoff disconnects the circuit within milliseconds if incoming voltage drops too low or climbs too high, then restores power once conditions return to normal. Diagnostic lights make it easy to see at a glance whether wiring at the pedestal is correct before you plug in for the night.

• Up to 4200 joules of surge suppression
• 3-mode protection: line-to-neutral, line-to-ground, neutral-to-ground
• Automatic voltage cutoff protects equipment within milliseconds of an out-of-range reading
• Response time under 1 nanosecond
• Metal locking ring for a secure pedestal connection
• Includes a wire brush for brass prong maintenance

A compact, pigtail-style option for RVers who want surge protection without the bulk of a full in-line unit.
