Abstract:
Automatic transfer switching apparatus and systems include a switching device including an input line, a sensor, and a parallel assembly of a solid-state relay and latching relay electrically connected with the input line. The solid-state relay is used to short the latching relay such that the latching relay can be opened and/or closed in an unloaded state while the input line is energized.
