Eaton Static Transfer Switch (STS) Eaton Static Transfer Switches are designed to enhance our line of advanced backup power management solutions, adding an increased level of power quality, flexibility, availability and reliability to create the best ups power protection infrastructure. Eaton Type II Static Transfer Switch (STS) Eaton Type II STS transfer electrical loads from one source to another, but provides more power availability. The Type II STS eliminates the chance of a loss of power to critical loads by properly coordinating with the electrical distribution system. During a fault condition, the Type II STS will continue to conduct current, allowing downstream circuit breakers to work selectively. Features and Benefits A patented transfer algorithm and robust electrical components ensure no single point of failure Unparalleled alarms, metering and diagnostics
