Make the most of your generator by adding a 100A automatic transfer switch (ATS) Single Phase for added security and peace of mind. This mains to generator automatic changeover switch seamlessly detects a power outage and start your standby generator. As soon as mains power is restored the transfer switch turns off the generator and connects back to the mains power supply.

How Does a 100A Automatic Transfer Switch Single Phase Work?

This transfer switch should be permanently installed close to the mains incoming supply to your building. In normal operation the load is supplying by the mains in the usual way but when the mains power is lost the ATS switch senses this loss and sends a signal to start your generator.

When the generator has started and is up to speed and frequency (normally around 8 to 10 seconds) this automatic changeover switch will automatically transfer the load to the standby generator set.

The automatic transfer switch will continually monitor the mains power and when this returns it will transfer the load back to the mains and initiate a cooling cycle and stop the generator. The transfer switch will then reset in readiness for the next power interruption.
