What is a change over switch? A changeover switch switches a house's electricity supply from the general grid power supply to a "generator system" in case of power outage. The changeover switch connects to the main power grid, generator or alternate source and the house wiring. When you switch or "Change over" all the power on that circuit changes from either Grid or Generator. (not allowing it to flow back into each other (Grid and generator)) Specifications: Model Number: SF263 Max. rated operation voltage (AC): 230.0 V Number of poles: 2 Rated current: 63.0 A Rated frequency: 60.0 Hz Switch function: Changeover Switch Voltage (Text): 230VAC Voltage type: AC
