Eaton Static Transfer Switch (STS)

Eaton Type II Static Transfer Switch (STS)

The Eaton Type II STS transfers electrical loads from one source to another while eliminating the chance of a loss of power to critical equipment by properly coordinating with the electrical distribution system. During a fault condition, the Type II STS continues to conduct current, allowing downstream circuit breakers to work selectively. By incorporating the Eaton Type II STS into your power infrastructure many UPS/building configurations are possible.
