    AUTOMATIC BUS TRANSFERS


    The Fairbanks Morse Defense and Ward Leonard Automatic Bus Transfers (ABT) allow for the flow of uninterrupted power supply to your emergency power source. Our ABT Switches are the trusted name in reliability, providing the necessary power when needed most.

    Our Automatic Bus Transfer (ABT) Switches provide for automatic or manual transfer of three-phase AC loads in cases where a low voltage or no voltage event occurs on a power supply. Our ABTs transfer the load from the emergency bus to the normal bus automatically or manually, depending on your unique requirements.
