What is an Automatic Transfer Switch?

Damage from a power outage can be significant to a home or business and to prevent this, standby generators are often maintained at a site to supply the emergency power needed. But if no one is present to start the generator and switch over the electrical load, damage can still occur. This is where an ATS comes in – it automatically accomplishes both generator start-up and load switching without the need for any kind of human intervention.

How does the ASCO 800 AMP 208V NEMA3R Automatic Transfer Switch function? 

• When a loss of power from the normal utility company source is detected by the Automatic Transfer Switch, it immediately signals the standby generator to start up.

• Once the standby generator has warmed up sufficiently to handle it, the electrical load is transferred by the ATS over to the standby source.

• While power is being supplied by the standby source, the ATS continuously polls the utility source to determine when power has been restored.

• When utility power has been restored and achieves a stable and acceptable voltage level, the ATS transfers the electrical load back to the utility source.

• The ATS signals the standby generator to go into cool-down mode for between 2 and 5 minutes to avoid any sudden shutdown damage.

• The ATS shuts down the standby generator.

Features of the ASCO 800 AMP 208V NEMA3R ATS

• The flush mounted, high grade aluminum cabinet houses a control panel with LED indicators that clearly identify the current status of both normal and standby power sources.

• An exercising feature is built in to the control panel, which allows testing of the standby source at regular intervals, with or without electrical loads.

• Time delays for detection of power loss are adjustable so that momentary losses can be safely ignored.

• The ATS is listed to the CSA C22.2 standard for automatic transfer switches, and to UL 1008 standard for power transfer switching.

• It meets NFPA 110 for emergency and standby power systems, and National Electrical Codes (NEC) 700, 701, and 702.

• The standard mechanical interlock prevents simultaneous operation of both normal and standby power source.
