Generac Standby Transfer Switches - TX Series

Generac Standby Transfer Switches - TX Series

Generac’s contactor type transfer switches are double-throw robust switch construction with inherent interlocks to ensure safe positive transfer between power sources. The contacts are silver composite for long life, resisting pitting or burning. The switches are rated for full load transfers in mission critical, emergency, legally required, and optional power systems.
The microprocessor based controller provides the customers with the flexibility to program a comprehensive group of set points to match the application needs. The controller has 4 programmable inputs and outputs as standard and is available with optional expansion boards for up to 20 programmable inputs and outputs. The LCD displays real time and historical information with time-stamped events. The integrated plant exerciser can be configured in off, daily, day of week, biweekly, and monthly intervals with user selectable run time. Standard features of the controller include three phase sensing on both sources, phase unbalance, phase reversal, load shed, emergency inhibit, and communications.
