The Eaton ATS Netpack is an automatic transfer switch rated at 30A, designed to automatically switch a connected load between two power sources — typically mains and a generator, or mains and a UPS/inverter feed — without manual intervention when the primary source fails. This is core load-shedding and backup-power infrastructure for South African businesses and homes running generators or battery-inverter systems: instead of someone flipping a switch when the power drops, the ATS senses the outage and transfers the load automatically, then switches back once the primary source is stable again. The 'Netpack' designation typically indicates network/remote monitoring capability on top of the base switching function, though the specific monitoring features aren't detailed in this listing.
