1000 AMP ASCO Transfer Switch, 3 Pole NEMA3R 208V
ASCO ATS Series 300 3ATSA31000CG0F

Whatever your business, you need to ensure you have a constant flow of electrical power for your operations to run as they should. Should there be a power failure, you could be in serious trouble as any downtime can have severe consequences on your business. Unfortunately, power outages can and do happen at any time, for all sorts of reasons. To ensure you're supplied with electricity 24/7 to keep your business running, you need to invest in an emergency power backup system. While of course this includes an engine generator, you also need an Automatic Transfer Switch (or ATS) in order to transfer the load from the utility power to the generator. 

What is an Automatic Transfer Switch?

An ASCO Series 300 Automatic Transfer Switch works in conjunction with your engine generator to ensure you have electrical power to your business premises at all times. During a power outage, the Automatic Transfer Switch transfers the load to the generator, and then transfers it back once utility power has been restored. The automatic element ensures that all this is done smoothly and with virtually no downtime. 

How does the ASCO Series 300 Automatic Transfer Switch function?

• The ASCO Series 300 Transfer Switch comes with built-in control logic, which monitors the supply of power and detects when there are any interruptions. 

• The ATS will then automatically start the engine generator when it senses the utility power failing. Once the generator has reached the correct frequency and voltage, the ATS then transfers the load from the utility to the engine generator. This happens seconds after a power failure.

• Once utility power has been restored, the ATS will switch the load back automatically. After a time delay, the engine generator is then switched off. 

Features of the ASCO Series 300 Automatic Transfer Switch

• Compact design with 30 through 3000 amps. 

• The flush-mounted control and display panel is easy to read, and provides LED indicators for source availability and switch position. 

• Test and time-delay bypass switches are included as standard.

• An adjustable time-delay feature ensures that the switch is not incorrectly activated thanks to a brief utility power outage or a generator dip. 

• As the ATS derives its operational power from the source to which the load is being transferred, it won't transfer power to a dead source. 

• Intuitive design prevents the ATS from being in contact with both power sources at the same time, and from stopping between power sources. 

• Meets all appropriate codes and standards in terms of safety and performance.
