Asco 940 Automatic Transfer switch. 480/277 volt 3 phase. Used. Cabinet 31" high by 18" wide by 12" deep. Includes manual. This unit worked just fine when the building was upgraded to a bigger panel. Was only used for a few years. Has been in storage inside the building for several years. This panel automatically starts generator, transfers load to generator, and when power is restored it transfers back and turns off generator. It can be programmed to test run generator once a week.
Please do not compare to manual transfer switches. This is fully automatic. Does not need any human interaction. CASH only.
DO NOT ask if still available. If you see the ad, it is available.
