Automatic Transfer Switch – 100A 3 phase 400-415VAC
This device is 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 this panel 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 panel will automatically transfer the load to the standby generator set.
The system 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 system will then reset in readiness for the next power interuption.

- 3 Pole mechanically & electrically interlocked pair of contactors.
