Dicor Electronic Surge Protectors

Guard Your RV's Electrical System with Dicor Power Surge Protectors

Dicor has been a trusted name in the RV industry since 1984, and their Dicor Power line of electronic surge protectors brings that same commitment to quality directly to your RV's electrical system. Whether you're plugging into a busy campground pedestal or a private hookup, campsite power quality can vary wildly — and that unpredictability can be devastating for your RV's sensitive electronics, appliances, and onboard systems.

The Dicor Power Line: 30-Amp and 50-Amp Protection

Dicor Power surge protectors are engineered to protect your RV investment from dangerous voltage levels and power surges, with options including a 30-amp circuit analyzer plug, a 30-amp pigtail, and a 50-amp pigtail — each varying in joule protection level.

• 30-Amp Plug Protector: Rated for up to 1,050 joules of surge suppression , this compact plug-style unit is an accessible entry point for lighter-duty 30-amp RV setups.
• 30-Amp Pigtail Protector: Rated for up to 4,200 joules of surge suppression , the pigtail design gives added flexibility when connecting to a pedestal.
• 50-Amp Pigtail Protector: Rated for up to 5,000 joules of surge suppression , this heavy-duty option is built for large motorhomes and fifth wheels with high-demand electrical loads.

Smart Features That Set Dicor Apart

Dicor doesn't just stop surges — their protectors actively monitor your hookup before you ever connect your RV's power cord. Visible diagnostic lights detect wiring faults such as line to neutral, line to ground, and neutral to ground prior to hooking up an RV. This pre-connection fault detection is a critical safety step that can prevent serious damage to your rig.

Response time is less than 1 nanosecond. If input voltage drops below or exceeds the set voltage range, the circuit will be disconnected to protect electronic equipment within milliseconds — and once voltage stabilizes and returns to normal, the circuit will restore power automatically.

The 50-amp model also features 5-mode surge protection, covering line 1 to neutral (L1-N), line 2 to neutral (L2-N), neutral to ground (N-G), line 1 to line 2 (L1-L2), and line to ground (L-G).

Each surge protector comes equipped with an automatic shut-off/on, easily visible surge indicator and diagnostic lights, incorrect wiring fault indicators, and a limited lifetime warranty.
