Switchgears

NUCON Transformers are proven as global technology in transformer.

On Load Switch Fuse Changeover

NUCON Switch fuse Changeovers are manually operated 4 pole switch fuse with compact design for application in low voltage distribution circuits and motor circuits. These comprise of two On Load switch Disconnectors, which are coupled together and are mechanically interlocked with common outgoing through protection of each & individual phase with HRC fuses. The Switch is compact & suitable for AC 23 A duty.

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.
