The Schneider Electric WTSH63-4N2 is a 4-pole automatic transfer switch rated for 63A current, typically used for 3-phase AC power systems. This switch allows for automatic transfer of electrical loads between two sources (e.g., utility mains and generator), ensuring continuous power when one source fails.
