On Load Switch Disconnectors (Load Break Switches)
NUCON On load Switch Disconnectors (Load break switches) are manually operated 4 pole switches with compact design for application in low voltage distribution circuits and motor circuits. the switches are compact and suitable for AC 23A duty.
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.

Salient Features
While breaking the circuit, guaranteed sufficient air sectioning clearance.
Utilization category - AC 23A.
Strong endurance and resistance to heat (Tropicalised).
Flag indicator for two stable positions (I-O) & possible switching on or off, on load, there by fulfilling the roll of switching device.
All current carrying parts are of special grade E.T.P. Copper and with silver plated.
Knife type contact system with self wipe feature allows cleaning of contact during each operation, calling for lesser maintenance and longer life.
