Automatic Bus Transfer Switches

Ward Leonard 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. The Ward Leonard ABT product line has options from that range from 50-Amp to 600-Amp loads.
