On Load Changeover Switches Compact Version
NUCON range of co-series compact version On load Changeover swiches are manually front operated four pole switches with very compact design which helps to save the space in panel boards resulting in low csting of panel boards. These comprise of two On Load Switch Disconnectors, which are coupled together and are mechanically interlocked with common outgoing. These are used in low voltage distribution circuits and motor circuits and motor circuits and at places where continuity of supply is necessary for switching from main supply to an alternate source of supply and vice versa.

ALL CO-SERIES Switches are capable of making, carrying & breaking currents under normal circuit conditions, which may include operating under overload conditions and also carrying currents under specified abnormal circuit conditions such as short circuit for a specified time.
