Emerson Network Power > EMEA > Products > Power Switching and Controls > Power Transfer Switches > ASCO Series 286 Non-Automatic Power Transfer Switch

The ASCO Series 286 Non-Automatic Power Transfer Switch is generally used in applications where operating personnel are available and the load is not an emergency type requiring automatic transfer of power. The power-switching mechanism and controller of ASCO Series 286 is the same hardware used on the highly reliable ASCO Series 200 transfer switches. As a standard, the ASCO Series 286 is furnished with a momentary-type selector switch to initiate transfer and retransfer. It can also be arranged for remote control via ASCO's communications products.
