Automatic Transfer Switches (ATS)


Since 1930, GE has designed and manufactured Automatic Transfer Switches (ATS) – products specifically designed to keep critical loads energized and protect personnel, facilities and businesses against losses. GE’s Zenith builds Low and Medium Voltage switches from 40A up to 5000A for applications requiring the dependability and ease of operation found in a power contactor switch UL1008.
