Keep your RV’s 30-amp systems safe from electrical hazards with this hardwired surge and voltage monitoring device. Continuous monitoring watches incoming shore power, automatically cutting supply if voltage drops below 104V or climbs above 132V—protecting furnaces, refrigerators, air-conditioning units, and sensitive electronics.

When power interruption occurs or a fault is detected, an internal time delay allows air-conditioning equipment to stabilize before reconnection. The unit incorporates multi-mode surge defence with indicators for reverse polarity, open neutral, open ground, and accidental 240-volt conditions.

• 30 amp, 120 volt hardwired installation
