About the project
For Selgros Hypermarket Brăila, KRONTAB modernized the main low-voltage distribution infrastructure by replacing the existing main switchboard with a new Main Electrical Switchboard configured with two 2000 A power sources and a 2000 A bus coupler.
The intervention aimed to improve safety, reliability and continuity of power supply in a large-scale commercial facility characterized by a high number and wide variety of loads, as well as the need for continuous operation of essential systems.
In addition to the main distribution system, 6 sub-distribution switchboards of different ratings were manufactured and equipped to supply specific installations and loads, including the “pauză mică” area, smoke extraction system, fire pump station and boiler room, as well as other auxiliary circuits.
The solution was implemented using Schneider Electric equipment, configured for distribution, protection and safe operation of the installation.
Benefits:
Built around the requirements of each project.
Control over the entire manufacturing process.
Equipment and systems from established manufacturers.
Every switchboard is inspected and tested before delivery.
Reliability designed for long-term operation.
Supplier of Equipment Used
Implemented solution
The central element of the project was the replacement and modernization of the Main Low-Voltage Switchboard, which serves as the primary electrical distribution point for the hypermarket.
The new TEG is configured with two independent power sources, each rated at 2000 A, together with a 2000 A bus coupler, providing flexibility in managing the main distribution system and allowing the installation to operate in different supply configurations.
The architecture with two sources and a bus coupler enables distribution sectionalization and increases system availability, which is particularly important in a commercial facility where a power interruption could simultaneously affect numerous systems and items of equipment.
The switchboard integrates Schneider Electric equipment for distribution and protection, with adjustable protection settings and protection coordination across the different distribution levels, helping limit the effects of a potential fault.
The modular construction and internal organization facilitate access to the equipment and allow inspection and maintenance operations to be carried out in a clear and structured manner.
The main distribution system is complemented by 6 electrical sub-distribution switchboards of different ratings, sized and configured according to the characteristics of the loads they serve.
These switchboards provide local power distribution to the various hypermarket installations and allow functional separation of the loads, contributing to safer operation and limiting the impact of a potential fault.
Each switchboard integrates the equipment required for distribution, protection and control in a configuration adapted to the function of the installation it serves.
Circuit organization and clear component identification facilitate both day-to-day operation and subsequent inspection and maintenance activities.
A dedicated electrical switchboard was installed for the smoke extraction system, providing power supply, protection and control for the associated equipment.
Given the role of this system in the building’s fire safety strategy, separation into a dedicated switchboard allows clear circuit management and integration of the functions required for system operation.
The switchboard is configured to supply and protect the loads specific to the smoke extraction system, as well as to provide the control and signaling functions specified in the project.
A dedicated switchboard was installed for the fire pump station, integrating the circuits required to supply and protect the associated equipment.
The solution provides functional separation of this critical load from the building’s other installations, contributing to clear and controlled operation of the electrical infrastructure.
Through dedicated circuit organization, the switchboard facilitates system status checks and the technical interventions required.
The boiler room switchboard provides power supply and protection for the installations and equipment required for operation of the hypermarket’s heating system.
The configuration integrates the distribution, protection and control equipment required for the loads served and allows this installation to operate independently from the other technical areas.
Separating the distribution into a dedicated switchboard simplifies operation, circuit identification and maintenance activities.
The switchboard dedicated to the break room provides distribution and protection for the electrical circuits serving this area of the hypermarket.
The switchboard configuration is adapted to the loads served and integrates the required circuits in an organized structure, with dedicated protection and clear identification of the outgoing feeders.
