MCB CHANGEOVER SWITCH



< Back


Polycab MCB Changeover Switch is a manual operated changeover switch which finds its application in switching load between two power supplies. MCB Changeover switch finds wide applications in industries as well as in domestic area specially in Individual Bungalow(IB) for use in low voltage distribution circuits, wherever continuity of supply is necessary. It is used for switching to an alternate source of supply from main supply and vice – versa. The changeover switch comes in 2P and 4P versions, for single and three phase application respectively. It has three positions ( I-O-II) with centre-off. They are switch disconnectors with independent manual operation, capable of making, carrying and breaking currents under normal circuit conditions.
