What is an Automatic Transfer Switch?

When your primary source of power fails, you need fast and seamless transition to your auxiliary or backup power source even when you aren’t around. An automatic transfer switch monitors your primary power source and tells your generator to start in the event of a power outage.

ASCO 100AMP Series 185 Transfer Switch Performance:

The compact and dependable ASCO 100AMP Automatic Transfer Switch(ATS) provides your home or business with continuous power, ensuring all your most important electrical loads and appliances keep operating in the event of a power outage or interruption. When the ASCO 100AMP ATS detects a loss of utility power, it completes a series of steps to ensure your most critical systems continue to operate:

  1. Immediately after detecting a power failure, or based on your criteria, the Series 185 ATS signals your backup generator to start and prepares to accept the electrical load. 
  2. Within seconds, power is restored to critical systems, appliances and devices. 
  3. Utilizing a Group 4 controller, the Series 185 ATS continues to monitor your utility power source for availability and stability. Once it reaches acceptable levels for a preset period of time, the 100AMP Automatic Transfer Switch will reconnect your systems to your primary power source.
  4. Your generator will continue to run for a cool-down period of two to five minutes before it stops completely. The Series 185 ATS will continue to monitor your utility power to ensure continuous operation.
