How SELVO TPN Phase Selector Enclosures Ensure Master Seamless Power Switching
In today’s fast-paced world, uninterrupted power supply is critical for both residential and commercial spaces. Power outages or fluctuations can disrupt daily activities, damage equipment, and cause significant losses. Now presenting SELVO TPN Phase Selector Enclosures—an innovative solution designed to ensure seamless power switching and optimal energy flow. These enclosures intelligently manage phase selection, guaranteeing a reliable power supply even during power outages. Applicable for use in three-phase power supply systems, Engineered for efficiency, durability, and safety, SELVO TPN phase selector enclosures are a game-changer for power management. In this blog, we’ll explore how these enclosures work, their key benefits, and the types.
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-Way 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 to that of SELVO SPN PHASE SELECTOR ENCLOSURE, which is that 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 inputs to an output load.
This working principle is the 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 the input terminals of the first rotary switches A1, A2 & A3 and the output load terminal of each rotary switch is connected to output terminal, through which the wiring will be done to equipment.
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 .
TPN PHASE SELECTOR ENCLOSURE CURRENT RATINGS
The SELVO TPN Phase selector enclosures are available in 4 different current ratings to cater to different load demands starting from 32A, 40A, 63A & 100A. Also, refer to this blog for more clarity on rotary switches https://electfyhub.com/selvo-cam-operated-rotary-switches-wide-range/.
