Automatic Changeover

We are manufacturer of wide range of Automatic Changeovers like Single Phase Changeover, Three Phase Changeover and Automatic phase-changer. Our range of change-overs finds wide application in industries as well as in domestic sphere for use in low voltage distribution circuits, wherever continuity of supply is necessary, for switching to an alternate source of supply from main supply and vise-verse. It is provided of switch dis connectors with independent manual operation, capable of making, carrying and breaking currents under normal circuit conditions, which may include operating overload condition and also carry currents under specified abnormal circuit conditions such as those of short circuit for a specified time.

Model Number: RTCS - 30/ RTCS - 60
We offer three phase automatic changeover cum phase selector RTCS - 30/ RTCS - 60. Enhanced design of these automatic changeover enables their relay top when they are in “on” position only, while they are being used in generators. At the time of functioning on main supply, the relay remains in “off” position. These changeover take minimal switchover time for main supply so even sensitive electronic equipments do not get disconnected during the switchover.

 

Product specifications:

 

  • Auto change of gen-set / main line
  • Auto stop of gen-set
  • Auto phase selector
