We provide On Load Changeover Switches (Compact Version), which are basically a 4 pole switch and are manually operated. Developed in compliance with IEC-947-3IS: 13947 Part (I&III) - 1993 and IEC: 664 quality standards, these switches saves the space in panel boards resulting in low costing of panel boards. Our range includes two On Load Switch Disconnectors that are joined together and are mechanically interlocked with common outgoing. These compact designed On Load Changeover Switches are mainly used in low voltage distribution circuits and motor circuits and at places where continuity of supply is required for switching from main supply to an alternate source of supply and vice versa.

Moreover, our range is 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.


  • Compact & Standardised sizes for range 63 A - 3150 A as compared to leading indigenous makes, thus saves panel space & cost.
  • While breaking the circuit, guaranteed sufficient air sectioning clearance.
  • Protection against over currents & short circuit fault of high rupturing capacity upto 80 KA.
  • Strong endurance & resistance to heat (Tropicalised).
  • Phase barriers between each phase terminal.
  • Flag indicator for three stable positions i.e. (I-O-II) & possible switching from one source to the other, on load, thereby fulfilling the role of switching device with interlocking protection for two modes of supply, one from electricity board & other from standby source i.e. generator and providing back up.
  • The shorting link can be connected on either side to facilitate interchangeability of line and load.
  • Auxiliary contacts up to 2 NO & 2 NC for signalisation & interlocking.
  • The moulded body's raw material is glass fiber reinforced polyester (SMC), having high mechanical & dielectric strength.
  • Strong & ergonomic operating handle with door interlock & padlock facility.
  • Utilization category -AC 23 A.
