Perko Compact Medium Duty Battery Selector Switch

The Perko Compact Medium Duty Battery Selector Switch is rated 315A continuous and 450A intermittent, on a 4-inch by 4-inch face.

The compact 4-inch square face is the reason to choose this over the standard selector, and it is often what decides the installation. Battery switches go on a bulkhead in a locker or engine space, and the available flat area is whatever the structure left. Four inches square fits places a larger switch will not.

Three hundred and fifteen amps continuous is higher than the medium duty rating despite the smaller housing. Comparing switches by size rather than by rating will mislead here, and the specification is what matters.

It selects between banks and acts as a main disconnect, covering both functions from one control. A polycarbonate body with brass terminals suits marine installation, with ignition protection for appropriate onboard spaces across 6 to 32 volt systems. Explore more battery switches.
