33 TECH TIPS Surge Guard® models 76-9739 (34931) (2450 Joules) and 769740 (34951) (4200 Joules) provide full electrical protection for any RV type and are highly recommended for larger towables and motorhomes. With a new, brighter, easy-to-read LCD display, these models provide a textual information display that does not require code interpretation. Real time voltage and amp draw are continuously displayed on the LCD screen. Power is automatically disconnected if the following conditions are present: low/high voltage, open ground, open neutral, reverse polarity, and overheating of plugs. The incoming power is constantly monitored, allowing for automatic reset when acceptable power is restored. These models also include a surge status LED indicator. Both the Surge Guard 30A 76-9739 (34931) and 76-9740 (34951) can detect and protect against elevated ground line currents that are generated inside of the RV. New patent-pending technology allows the Surge Guard 50A Model 34951 to detect an open neutral condition inside the RV. The Surge Guard device can detect open neutral on the common neutral line from the device to the main breaker panel. When this fault occurs, there is a dramatic swing in the voltages in both Leg 1 and Leg 2, where one leg will swing to extremely high voltage and the other leg will swing to extremely low voltage, causing immediate damage to all electronic devices that are plugged in inside the RV, unless the Surge Guard 50A Model 34951 is in use. “Our goal is to provide the highest level of electrical protection for RV owners to safeguard their families and investments from the dangers of electrical faults,” Southwire’s Director of Sales, Mobile Power & Electrical Safety, Bobby Raatz Featured Products! Introducing the next generation of surge protector technology, redesigned to detect electrical issues from both the power source and inside the RV.* Check out our new limited lifetime & connected equipment warranties. 30A Full Protection Portable 76-9739 Model 34931 50A Full Protection Portable 76-9740 Model 34951 Available for these products: 19-1366 (44260), 19-1369 (44270), 194129 (44280), 19-4130 (44290), 74-8584 (44380), 71-8585 (44390), 19-2545 (34830), 19-2546 (34850), 76-9739 (34931) and 76-9740 (34951), 18-7669 (35530), 18-7670 (35550), 71-8593 (44300) Innovation New Product Models 76-9739 (34931) and 76-9740 (34951) * ®, ™, and * Trademark of Southwire Company, LLC.
