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.
