Southwire | 30 Amp Surge Protector | 34931 | Bluetooth | Compatible with Wireless LCD Display

Protect your RV's electrical system from the leading cause of appliance and electronics damage with the SouthWire Surge Guard 30-Amp Surge Protector (Model 34931). This advanced surge guard does far more than block voltage spikes — it actively monitors your 30-amp shore power for the voltage irregularities, wiring faults, and pedestal problems that quietly destroy RV gear, giving you genuine peace of mind every time you plug in.

Comprehensive Protection, Not Just Surge Suppression

The 34931 watches for the full range of dangerous electrical conditions and protects your rig against:

• Power surges and spikes
• Low voltage (under 102V) and high voltage (over 136V)
• Frequency irregularities
• Reverse polarity
• Open ground and open neutral
• Elevated ground line current
• Overheating plug or receptacle

These are exactly the faults a basic surge strip can't catch — and exactly what damages air conditioners, converters, and sensitive electronics over time.

Bluetooth Monitoring

The 34931's Bluetooth capability lets you monitor your RV's electrical status wirelessly when paired with the optional SouthWire Surge Guard Wireless LCD Remote Display (sold separately) — so you can check power conditions from inside the coach instead of crouching at the pedestal.

Smart Delays Protect Your Equipment

A 10-second startup delay and a 128-second fault delay protect sensitive equipment like A/C compressor motors from the rapid cycling that can damage them — an important feature that separates a real protective device from a simple surge plug.

Built for the Outdoors, Built to Stay Put

The weather-resistant design is made for outdoor use at the pedestal, and a lockable security ring adds theft protection so your investment doesn't walk off while you're away from the site.

Industry-Leading Warranty

The 34931 is backed by SouthWire's Limited Lifetime Warranty, reflecting real confidence in its durability and long-term performance.
