Add the convenience of managing 12V 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. This auto-release switch is ideal for applications that use an alternate relay to switch batteries. An example being, a relay set up to protect battery life by turning them off at a certain voltage levels. Key Features Included SPST Contura styled remote switch (Blue Sea Systems 2155) makes battery switching as easy as pushing a button Can be controlled using SPST or SPSD switches for applications where a normally open relay is desired 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 Not recommended
