Automatic Transfer Switch Supplier & Manufacturer

It moves a load between a normal supply and a standby source automatically when the primary feed fails or becomes available again, keeping connected equipment powered.

It is required wherever continuity matters during an outage, such as critical commercial loads, backup generator systems, and industrial processes that need an alternate feed.

Inspection of the normal source is used to detect loss or return of supply, and the transfer logic then initiates the changeover to the alternate source according to the defined sequence.

Interlocking prevents both sources from being connected at the same time, avoiding unintended parallel connection that could create circulating currents or fault paths between supplies.

The rated current and pole configuration are selected to match the load being transferred, with the transfer mechanism designed to handle the same switching duty as the protected circuit.
