Switchgears

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.
