The WaveStar TFA Static Transfer Switch is the only True Front Access Static Switch which enables Installation, Maintenance, Service and IR Scanning from the front of the enclosure. The innovative compartmentalized cabinet lowers total cost of ownership by simplyfying installation, and making maintenance safer by reducing the potential for arc flash. The WaveStar TFA Static Transfer Switch supplies critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the WaveStar TFA switch automatically transfers to an alternate source within a quarter cycle and without interruption of power to even your most sensitive critical loads.
