Siemens 6ES7 390-1AE80-0AA0 Mounting Bracket

Siemens 6ES7 390-1AE80-0AA0 is a 480 mm profile rail designed as a mounting accessory for SIMATIC S7 automation systems, providing a rigid backbone for modular hardware in industrial control cabinets. Catalogued by Siemens as a 6ES7 390-series profile rail with a fixed 480 mm length, it is designed to accept fellow S7-300/400 modules and backplane assemblies, ensuring precise alignment and secure attachment within compatible enclosures. As an official Siemens component, this rail supports standard cabinet layouts where space efficiency and orderly arrangement of CPUs, I/O blocks, and extension cards are critical for reliable operation. Use cases include building compact rack installations in electrical cabinets or switchgear where a dedicated mounting rail is required to maintain modular spacing and chassis integrity. The 6ES7 390-1AE80-0AA0 rail is designed to accompany standard SIMATIC S7 architectures, providing a consistent mounting solution for systems that rely on a stable, uniform rail to organize multiple modules along an enclosure’s width. In Siemens’ catalog materials, it is referenced explicitly as a “Profile rail, 480 mm,” underscoring its role as a fixed-length mounting solution within the 6ES7 390 accessory family.
