Description

Generac’s patented* contactor type transfer switches are double-throw robust switch construction with inherent interlocks for 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, le-gally 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 two programmable inputs and one programmable output as standard and is available with an optional expansion board for up to four programmable in-puts and outputs. The LCD displays real time and historical infor-mation 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 un-balance, phase reversal, load shed, emergency inhibit, and communications.
