Battery selector switch 771-SFD 400A 48V with field disconnect 4 position

Pro Installer 400A Selector with Field Disconnect Battery Switch - MC10 Surface, Rear or Front Mounting
771-SFD

Power requirements on boats have increased, and these 2 Selector switches offer high power capacity (400 amps continuous), the ability to easily fit doubled cables, and conform to the industry standard mounting footprint (Guest, Perko, Blue Sea). 
Please note selector switches will not separate electronics from harmful engine starting spikes. 
Note: 771-S is replacing 721.

This innovative (Patent Pending) switch combines the functions of 3 battery switches into one (House,
Start, and Emergency Parallel) to intuitively manage 2 battery banks and 2 loads. A unique safety
position isolates one load e.g. House “On”, Start “Off” in case of engine malfunction, so an emergency
radio call can still be made. Significant savings in both space and installation cost can be made, without
compromising functionality or safety.
