Automatic and Manual Transfer Switches

Transfer Switches for a Range of Applications

Transfer switches ensure that when you have a power outage, your critical equipment keeps running.

The electrical switches transfer loads between different power sources - some types do this automatically, while others get run by an operator. Some types of switches, on top of doing the actual “switching,” also tell the backup generator to start running when the primary source of power is lost.

The equipment is applicable to a wide range of environments, ranging from residential, agricultural and light commercial applications to the critical power needs of healthcare, financial and data center facilities. In some facilities, switches need to be tested without interrupting power to the load - those will require bypass-isolation configurations. In some applications, integrated solutions are required - you’ll need transfer switch load panels, circuit breakers and voltage surge suppression pre-wired in compact packages.

Vertiv offers a range of manual and automatic transfer switches, from those needed by smaller facilities all the way to those required by critical applications.
