Generac Transfer Switch Group - Automatic Transfer Switches
Automatic Transfer Switches are an integral part of the power generation process, allowing smooth and immediate transfer of electrical current between multiple sources and the load. When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility’s system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation.

The transfer switch senses when utility power is interrupted, and starts up the generator if the utility power remains absent. In about five to ten seconds, when the generator is producing full power, the transfer switch disconnects the load from the utility and connects it to the generator, restoring electricity to the load. The transfer switch continues to monitor utility power, and when it is restored, switches the load from the generator back to the utility. Once the generator is disconnected, it goes through a cool-down routine and is automatically shut down.

Generac's automatic transfer switches are designed to be simple to monitor, operate and maintain. All controls needed for daily use are conveniently located on the front door, where bright lamps indicate the switch position. All components are front adjustable and front removable for optimum serviceability. As an extra measure of safety and quality, Generac's transfer switches are UL Listed by Underwriters Laboratories for use in emergency power systems. They are also CSA certified by the Canadian Standards Association.

Generac's expertise in the design and manufacture of automatic transfer switches (ATS) is considerable. The company has produced its own fully instrumented 100 to 2600 amp switches since 1983.

Generac transfer switches are carefully constructed and tested to assure superior performance. By combining them with our own generators, we're able to offer a complete power generation package that we support and warrant.

Line Failure Sensing Circuitry monitors all phases of the utility service with dropout and pickup points		Programmable Exerciser— Permits selection of "days of the week" and "time of day." Visible digital chronograph used to select times. Allows exercising from one to seven days a week
Utility Interrupt Delay Adjustable timer overrides momentary line failure		Exterior Meter Package— Enables user to monitor the system parameters with the door closed
Engine Warm-up Timer Adjustable timer allows engine to operate at no load before the transfer switch transfer the load to the generator set		Fourth Pole— Fourth pole for switching the neutral conductor
Engine Warm-up Bypass A switch allows the transfer switch to transfer the load to the generator as soon as the preset voltage and frequency levels are reached		Preferred Source Selector Switch— Ability to select which power supply will be considered the normal source
Minimum Run Timer Determines the shortest period of time the generator will run and ensures adequate exercise periods		Manual Selector Switch— 3 positions: normal, automatic and standby
Return to Utility Delay Adjustable timer keeps the load on the generator set until a stable utility line is present		Manual "Return to Normal" (electrically operated)— Ability to select when the switch will transfer back to normal
Engine Cool-down Timer Adjustable timer allows the engine to run at no load after the transfer switch transfers the load back to the utility line		Remote Automatic Control Circuit— Ability to start the generator and transfer the load to emergency from a remote location
Frequency and Voltage Set Sets the minimum frequency and voltage required before the transfer switch will be allowed to transfer the load to the generator set.		Signal before Transfer Contacts— Adjustable from 0.1 - 10 seconds. Signals to special loads prior to transfer. Often used to prevent elevators from stopping between floors
		Generator Mounted Transfer Switch— Transfer switch may be mounted on the GenSet for both indoor and outdoor application
