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.

Highly Durable
Higher Electrical & Mechanical life > 10000 Operation
Construction
The entire switching mechanism along with the fixed and moving contact assembly are housed in FR thermo plastic moulded case / cover, having high dielectric strength, excellent mechanical & thermal properties. The switching mechanism is double break type. The contacts tips are made of Silver Cadmium oxide for long electrical life, sustained current carrying capacity and they ensure temperature rise is within specified limits.
