Changeover Distribution Panel

Changeover Panel , also known as an Automatic Transfer Switch (ATS) Panel or Manual On Load Changeover Panel, is an electrical control system designed to seamlessly switch power supply between two or more sources, such as the main grid, backup generator, or solar power system. This ensures uninterrupted power supply during outages or planned maintenance, making it essential for critical applications in industrial, commercial, and residential settings.

Changeover Panels can operate manually or automatically, with automatic versions equipped with intelligent controllers to detect power failures and switch to an alternative source without human intervention. These panels are engineered for reliability, safety, and ease of use, ensuring continuous power delivery while protecting equipment from electrical faults.

  • Seamless Power Switching : Automatically or manually switches between power sources (e.g., grid to generator) to ensure uninterrupted operation.
  • Automatic Transfer Switch (ATS) : Intelligent controllers detect power outages and initiate switching within milliseconds (for automatic panels).
  • Manual Override Option : Allows manual switching for maintenance or specific operational needs.
  • Robust Protection : Equipped with circuit breakers, fuses, and surge protectors to safeguard against overloads, short circuits, and voltage spikes.
  • IP-Rated Enclosures : Offers IP54 (indoor) or IP65 (outdoor) protection against dust, moisture, and harsh environmental conditions.
  • High-Quality Construction : Built with 14/16 SWG CRCA sheets or stainless steel, powder-coated with a 7/9-tank process for corrosion resistance.
  • Real-Time Monitoring : Includes digital meters and indicator lights for monitoring power source status, voltage, and current.
  • Customizable Configurations : Available in single-phase or three-phase systems, tailored to specific load and power source requirements.

Changeover Panels are equipped with essential components to ensure reliable power switching and system protection. Key components include:

  1. Automatic Transfer Switch (ATS) Controller : Monitors power sources and automatically initiates switching in case of failure (for automatic panels).
  2. On Load Manual Changeover Switch : Manual or motorized switch to toggle between power sources (e.g., grid, generator, or solar).
  3. Circuit Breakers (MCBs/MCCBs) : Protect the system from overloads and short circuits.
  4. Busbars : High-conductivity copper or aluminum busbars for efficient power distribution.
  5. Surge Protection Devices (SPDs) : Safeguard against voltage surges caused by lightning or grid fluctuations.
  6. Metering Devices : Voltmeters, ammeters, or multifunction meters to monitor electrical parameters of each power source.
  7. Indicating Lamps and Control Switches : Provide visual feedback on power source status (e.g., Grid ON, Generator ON) and enable manual operation.
  8. Relays : Control switching operations and provide fault detection for enhanced reliability.
  9. Wiring and Terminals : FRLS/HR FR insulated wires and stud-type or DIN-rail terminals for secure connections.
  10. Enclosure : Weatherproof, IP54/IP65-rated enclosure made of CRCA steel or stainless steel for durability.
