The ASCO 185 Series automatic transfer switch (ATS) are 2-wire control switches that are compatible with all 2-wire start systems from all manufacturers. The switch monitors incoming utility power. When the utility power fails it starts the generator and transfer the emergency load onto the generator. After the utility power is restored it will transfer the load back to the utility source, cool down the generator and then return to a standby mode. The ATS has an exercise circuit that tests the generator system every week. The automatic test feature can be set under load or under no load.

The ATS includes a service entrance rated main line circuit breaker to save time and money during installation.
