SELVO TPN Phase Selector Distribution Boards : Importance in Electrical systems

The SELVO TPN Phase Selector MCB Distribution Boards play a pivotal role in modern electrical systems, ensuring efficient and reliable power distribution. Designed to handle three-phase power systems, these boards integrate a phase selector mechanism that seamlessly switches between phases, providing an uninterrupted power supply even during outages or fluctuations. Equipped with Miniature Circuit Breakers (MCBs), they offer enhanced safety by protecting circuits from overloads and short circuits. Widely used in residential, commercial, and industrial setups, SELVO’s innovative boards ensure optimal energy management, reduce downtime, and contribute to the overall stability and safety of electrical infrastructure. This article delves into the significance of these distribution boards and their contribution to modern electrical systems.

Working Principle of TPN Phase selector distribution board

The SELVO TPN (Three Phase Neutral) Phase Selector Distribution Board is designed to ensure uninterrupted power supply by manually selecting an available phase in case of phase failure or power outage in one or more phases. The current ratinsg to handle maximum load capacity can ne 40A , 63A or it can be even 100Amps .

TPN DISTRIBUTION : The TPN configuration includes three poles (R, Y, B phases) and a neutral connection. This allows for balanced power distribution in three-phase systems or independent operation of single-phase loads derived from the three-phase system.

CONSTRUCTION PART 

ENCLOSURE MATERIAL : Enclosures are fabricated in heavy gauge CRCA Sheets which have undergo seven tank treatment process and powder coated to ensure corrosion resistant and rusting , and also results in attractive appearance . The thickness of CRCA Sheets is 1.2 mm . 

High quality brass neutral and earth links to prevent temperature rise and promote safer operation .

CAM Operated Rotary Switches : Assembled with selvo cam operated rotary switches for phase selection which have been engineered and designed especially to meet the requirements of latest concepts in switching technology . 

Indicators :  The board typically includes phase indicators (LEDs) to show the status of each phase, making it easier for the user to monitor which phase is active or faults. 

MCB:

  • Each phase is equipped with an SELVO MCB to provide overcurrent and short-circuit protection. This ensures that the system is protected from potential damage due to electrical faults.
  • A dedicated neutral bar ensures proper distribution of the neutral connection across the circuits.

ISOLATOR : This device is used for switching on and off and are used at the incoming supply  

RCCB : This stands for residual current circuit breakers , which protects the electrical circuit from leakage protection . , also can be used in incoming . 

Wires : Selvo wires are used for connection , the distribution boards comes with duly wired . 

SELVO Phase Selector Distribution Boards is an electrical device for managing & distributing power across multiple circuits while providing ability to select between different phases in three phase system . This is crucial in areas with unstable power supply to ensure continued operation by switching to a phase that is active & stable . 
Once a phase is selected , power is distributed to connected circuits , they can accomodate up to 4 /6 /8 ways or circuits depending on the number of output loads . Each way or circuit is protected by its individual MCB ( Miniature circuit breaker )
