SELAM Technology

The SELAM product line includes:

• Main and secondary distribution boards (MDB, DB, SDB, etc.)
• Power control panels for technological electrical equipment (ASCU, SCC, MCC, etc.)
• Relay protection and automation panels (RPA)
• Reactive power compensation units
• Bus bridges for connection with power transformers and switchboard sections

Main Advantages of SELAM LVSG:

• High reliability, easy maintenance and installation, maximum operator safety
• Compact design and efficient use of installation space due to universal section sizes and high assembly density
• Various structural levels ensuring resistance to arc faults, earthquakes, impacts, and vibrations depending on operating conditions and environment
• Each SELAM panel is assembled from modules; modular design allows flexible adaptation to changing technical requirements
• Adaptation to new operating conditions is achieved by replacing or adding new modules
• Quick replacement and extension of functional units
• High degree of internal partitioning (up to 4b)
• Possibility to use components from leading domestic and European manufacturers; free configuration of functional blocks, and, if necessary, the use of custom non-standard modules according to customer requirements
• A high degree of combination flexibility, enabling almost any task to be accomplished

Standards

SELAM is manufactured in accordance with TU U 27.1-38549151-001:2020, IEC 60439, and DSTU IEC 60439.
