Product Usage

The Eaton automatic transfer switch with contactor bypass isolation operation is particularly effective in businesses that need safe electrical access, as well as businesses that routinely utilize auxiliary power for maintenance or performance testing. Automatic transfer switches are highly valuable in critical applications that cannot afford downtime or even a moment’s hesitation in electrical access, as switching to secondary power can be achieved in a fraction of a second.

The transfer switch creates stable connections with utility power and your business, routing them to portable or permanent generator systems. In the event of an outage caused by poor weather or utility outage, the switch will detect power loss and automatically switch to emergency or secondary power sources. When utility power once again becomes stable , or maintenance is completed, the automatic switch will reverse, returning primary utility power hands-free.

Automatic switches are necessary in many business applications, including data centers, the medical field, correctional facilities, retail and food service, as well as hotels and other hospitality service industries. Because of the speed and safety of automatic switches, you can rely on them to keep power stable at all times with no interruptions or loss under normal working conditions.
