This Perko Compact Battery Selector and Main Disconnect Switch uses a polycarbonate body with brass terminals, ignition protected for use on 6 to 32 volt marine electrical systems. It skips the key lock found on other models, keeping the footprint smaller.
It’s rated for 315 amps continuous, with a 450 amp intermittent rating for 5 minutes, a higher capacity than the standard medium duty switch despite its more compact size. A 3/8-inch terminal stud size accommodates larger battery cable lugs.
The switch measures 4 inches wide, 4 inches tall, and 3 inches deep. That’s sized to fit tighter mounting locations than a full-size selector switch would allow. Browse more battery management systems.
