What is an automatic transfer switch?
When you rely heavily on your electrical system, whether it’s for your home, your business, or otherwise, sometimes you can’t afford to take the time to throw a manual transfer switch to power your generator or other power source. In cases like these, it’s time for an automatic transfer switch. Automatic transfer switches and automatic generator switches can detect a loss of power and then transfer electricity from one source to another, all while isolating the generator and designated circuits from the rest of the electrical system.
How does an automatic transfer switch work?
Automatic transfer switches perform multiple actions very quickly as soon as an outage is detected. They can utilize either a “break before make” mechanism, which breaks the connection to the utility before connecting to the second power source, or a “make before break” mechanism, which creates the second connection before the first is broken.
Rugged, durable, and versatile, automatic transfer switches can be configured to only provide power to certain crucial, pre-selected circuits in an emergency situation. They are a common choice across industrial and commercial applications due to their convenience and reliability of transferring essential electrical loads.

Used wherever single phase power is needed, single phase automatic transfer switches safely transfer power from your utility to your standby power source. They are used for lighter electrical loads across residential and commercial applications for appliance and lighting circuits.
Since 3 phase power is typically used for heavier electrical loads, 3 phase automatic transfer switches are used for heavy duty applications. Common applications include industrial, agricultural, telecom, and anywhere you’d find heavy motor loads. Available across a number of voltage and amperage ratings, 3 phase automatic transfer switches are crucial to these sectors for delivering uninterrupted power.
