Camco’s 50 AMP Power Defender with PowerGrip handles help protect your RV from damaging low/high voltage levels and power spikes and surges. Camco’s Power Defender monitors incoming power, automatically disconnecting it when dangerous voltage levels are detected and automatically reconnecting once it stabilizes between 102-132 VAC. Reconnect delay protects sensitive equipment, such as AC units, by not rapidly cycling power. Water resistant unit incorporates integrated multilevel surge protection and diagnostic lights for visual indication of faults. The Automatic Power Reset helps protect your RV from low/high voltage, power surges, and incorrectly wired electrical boxes.
