SS Power Tech offers specially designed Subtech Automatic Changeover Switches which come with unique constructions. Theses switches have four breaks per pole thus resulting into faster Quenching of arc. The load and line can be connected on either side by virtue of isolation on both the sides. The switches manufactured at SS Power Systems are considered as the most trustworthy automatic changeover switches manufactured by any company.

Enhanced design of these switches enables their relay top when they are in “ON” position only, while they are being used in generators. At the time of functioning on main supply, the relay remains in “OFF” position. These switches take minimal switchover time for main supply so even sensitive electronic equipments do not get disconnected during the switchover. On resumption of main supply, the connected load is automatically shifted on mains.
