Blue Sea Systems 7700 ML-Series Remote Battery Switch, 12V, 500A Continuous

The Blue Sea Systems 7700 is an ML-Series Remote Battery Switch with Manual Control, designed to connect and disconnect a boat's battery bank from a remote location while retaining a manual back-up override at the switch itself. It is built for 12VDC systems and is rated for 500 amps continuous and 700 amps intermittent load, making it suitable for isolating house or engine battery banks on boats that need remote on/off control without running heavy cable to a helm-mounted switch. The unit's current-carrying components use a silver alloy contact material for reliable, long-term conductivity under repeated switching cycles.

Control is provided through an integrated rocker switch with indicator lights, so the operator can see switch status at a glance, and the manual back-up allows the battery connection to be operated directly at the unit if remote control power is lost. The compact housing measures 5.5 inches high by 3.75 inches wide by 2 inches deep, allowing installation in tight battery compartments, and the complete package includes the switch unit and an instruction manual.
