ATS Automatic Transfer Switch 63A
An Automatic Transfer Switch (ATS) 63A is a crucial electrical device designed to automatically switch the power supply from a primary source (such as the utility/grid) to a secondary or backup source (such as a generator or solar inverter) when the primary power fails. Once the grid power returns to normal, the ATS automatically transfers the load back to it without manual intervention — ensuring continuous power to your appliances, systems, and critical equipment.
Built for use in residential, commercial, and industrial environments, this ATS is rated for 63 A (amps), making it suitable for medium-to-high load applications including homes, offices, factories, clinics, and data centers.
