SELVO 40A Three Phase Neutral (TPN) Phase selector Enclosure

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 to 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.

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 SELVO TPN Phase selector enclosures are available in 4 different current ratings  to cater to different load demands starting from 32A , 40A , 63A & 100A 

Enclosure is fabricated in CRCA sheet protected with seven tank phosphate process and anti corrosive powder coating for the outer casting for attractive appearance.

LED indicator provision for showing indication through which phase power supply is carrying on .
