Blue Sea Systems 7700 ML-RBS Remote Battery Switch 12V 500A Manual Control

The Blue Sea Systems 7700 ML-RBS Remote Battery Switch brings push-button convenience to high-amperage battery bank management. This 500-amp magnetic latching switch enables battery switching under load from remote locations or via manual control, eliminating the need to access hard-to-reach battery compartments.

Dual Control Design:

The ML-RBS features both remote and manual operation for maximum flexibility and safety. The included SPST Contura-style remote switch (Blue Sea Systems 2155) mounts easily at the dash or nav station, requiring only light-gauge wire for installation. A built-in manual control lever with lock-out feature ensures you can always control the battery even if remote switch wiring is compromised. The sliding cover on the remote switch prevents accidental switching.

Key Features:

• 500A continuous rating with 700A intermittent capacity (5 minutes) and 1450A cranking rating
• Magnetic latching design with no parasitic draw while not actively switching
• Service lock-out feature prevents accidental current flow during electrical system maintenance
• 3/8" tin-plated copper studs for maximum conductivity and corrosion resistance
