CHANGEOVER SWITCH

 A changeover switch is designed to transfer a house (or business) electricity from the commercial power grid to a local generator when n outage occurs. Also known as “transfer switches,” they connect directly to the generator, commercial power supply or line, and the house.

The automatic changeover is installed where the main supply is of three-phase but the generator is either single-phase or three-phase. ... Automatic changeover shifts to the generator load automatically after the absence of all three phases of mains and when the generator is started.

Install a Changeover switch (about 63-100A depends on the load) near the main distribution board in the home. Connect the main power supply (Line and Neutral) as in coming to the first upper slots of Changeover Switch as shown in fig. Connect a 6 AWG (7/064″ or 16mm2)” cable wire to the lower two slots of the Changeover switch.

Changeover Switch. Automatic Transfer Switch. Onload Changeover Switches. Bypass Switch. Double Power Automatic Transfer Switches. Low Voltage Transfer Switches. Low Voltage Switches.

Changeover switch finds wide applications in industries as well as in domestic areas especially in Individual Bungalow(IB) for use in low voltage distribution circuits. Changeover switches are used to shift from one source of supply to another source and vice versa. The changeover switch comes in 2P and 4P versions, for single and three-phase applications respectively. It has three positions ( I-O-II) with center-off. They are switch disconnectors with independent manual operation, capable of making, carrying, and breaking currents under normal circuit conditions
