Manual/Auto Transfer Switch Panels

Manual transfer switches are the simplest means of transferring load between power sources. With break-before-make switching sequences, these switches cost-effectively transfer loads between utility and backup power sources.

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. Following the failure, the ATS automatically invokes the backup source to minimize power supply disruptions.
