The 75900 Double Pole Series 36 V High-Amp DPST Master Battery Disconnect Switches are
designed to handle two loads. This allows you to control two systems, such as the battery and
the alternator or generator field circuit, or to disconnect the positive and negative of the same
circuit. Depending on the model, these master battery disconnect switches may be capable of
handling two high-current loads or may be designed with one high-current circuit and one
auxiliary circuit for applications like secondary reporting of the switch's status.
All 75900 Double Pole series master disconnect switches feature a heavy-duty, plated-steel
housing, which makes them ideal for use in commercial vehicles. Plus, thanks to O-ring,
epoxy, and gasket seals on various models, it is easy to find a disconnect switch that stands
up to the conditions of your specific application.
