Blue Sea Systems 7702

Add the convenience of managing 24V battery banks remotely and the safety of a service lock-out

Blue Sea Systems designed the ML-Series heavy duty remote battery switch to make controlling large battery banks push-button convenient. Because of their size and cable requirements, conventional battery switches are typically located in lockers, or behind a seats and are difficult to access.

Installation of a remote switch has two benefits: it puts the control of the switch right on the dash or nav-station and it shortens heavy cables runs by putting the switching mechanism close to the battery. Included is a Contura style switch that requires only light gauge wire and will easily fit next to (if not match) other dash mounted switches. A sliding cover on the remote switch prevents accidental switching.

 The ML-RBS switching mechanism can be mounted close to the batteries to limit heavy gauge cabling. For added safety a manual control lever with lock out feature has been built into the ML series switches; you will always be able to control the battery even if the wiring to the dash mounted switch is compromised. The service lock-out offers a level of safety when working on the electrical system. Ideal for multiple helm applications.

Key Features

  • Included SPST Contura styled remote switch (Blue Sea Systems 2155) makes battery switching as easy as pushing a button
  • Ideal for boats with multiple stations that require battery control at each helm
  • 500A capacity is able to manage large battery banks
  • Manual operation possible if power is not available
  • Service lock-out to prevent accidental current flow while working on electrical system
  • LED output in switch allows switch state indications (requires optional LED panel)
  • Label recesses for bank identification
  • 3/8" Tin-plated copper studs for maximum conductivity and corrosion resistance.
  • Silver alloy contacts are very reliable for switching large loads
  • No parasitic draw while not actively switching
  • Can be used with MV-ACR to improve battery management features
  • Ignition protected for use in engine rooms of gasoline powered boats
  • Lifetime warranty
