MATERIAL USED FOR CONSTRUCTION

  1. ENCLOSURE MATERIAL : The enclosure is made from Cold Rolled Close Annealed (CRCA) steel, ensuring exceptional strength and durability. The outer surface is coated with high-grade powder to protect against corrosion, rust, and environmental wear and tear. Offers ingress protection IP 43 against dust and moisture for safe operation in varied environments.

  2.  Single Pole Three Ways Rotary Switches : The term single pole signifies that it will be used for single-phase applications, and three-way means a three-way rotary switch allows the user to select from three different input power supplies. If a power cut occurs in the first phase, then you must rotate the switch to any of the adjacent second or third phases that have the power supply.

  3.  WIRES : SELVO wires are used for connection , these are ISI marked as per IS : 694  , the CM/L number is 8800121550 .

     

  4. Connector : Connector is a junction for the connection of input power supply to rotary switches , which will be connected to the output load . The type is 4 way connector .

     

  5. Indicating lamps : Indicating lamps are fitted and duly wired , they provide indication  by glowing for the phase selected through which power supply flows  , here are the three lamps for each consecutive three phases .

Working Principle of TPN PHASE SELECTOR ENCLOSURE

The working principle is similar like of  SELVO SPN PHASE SELECTOR ENCLOSURE , which is If a power cut occurs in the first phase, then you must rotate the switch to any of the adjacent second or third phases that have the power supply.  The specific shape of the cam forces certain contacts to open and others to close. This re-routes the electrical flow from the different input to an output load.  

This working principle is same for the rest of the two rotary switches as well , the rotary switches are connected in series with each other . The input power supply of each phase is connected to input terminals of the first rotary switches A1, A2 & A3 and output load terminal of each rotary switches is connected to output terminal , through which the wiring will be done to equipments . 

the proper wiring is provided in the above image for reference . SELVO provides the pre wired TPN phase selector enclosure to ensure hassle free installation and at the affordable prices , you can check the mention link of amazon .
