Description
The Siemens 6ES73390-1AE80-0AA0 is a 482 mm (approximately 19 inches) heavy-duty aluminum mounting rail designed exclusively for the SIMATIC S7-300 and ET 200M modular automation systems. Unlike standard 35 mm top-hat DIN rails, this profile features an integrated structural slot with pre-threaded holes tailored specifically to accept the mounting screws of S7-300 central processors, power supplies, and I/O modules.

International Trade Regulations & Logistics Optimization
How do you optimize logistics for rigid structural components? Because a 482 mm metal rail cannot be bent or compressed, packaging dimensions are longer than standard electronic modules, which shifts the freight billing focus from dead weight to volumetric weight. To minimize these shipping expenses for international buyers in North America, Europe, and the Middle East, our logistics division secures these items in reinforced, low-profile tubes or boxes via DHL, FedEx, or UPS air freight networks.
We conduct all international business under Incoterms 2020 guidelines, providing standard pricing via EXW (Ex Works) or FCA (Free Carrier) terms to give procurement managers full authority over their chosen freight forwarders. For international customs clearance, our team supplies complete shipping manifests utilizing HS Code 76169990 (other articles of aluminum) to avoid border delays. Financial settlement options include wire transfer (T/T) and verified Letters of Credit (L/C).
6ES7390-1AE80-0AA0 Mechanical Installation Realities
On a recent retrofitting project involving an outdoor distributed control cabinet, a mechanical technician mistakenly assumed they could simply snap standard 35 mm DIN rail modules onto this hardware. Well, technically this rack is shaped similarly to a DIN rail, but only if you are looking at the upper hook lip. The bottom portion relies entirely on localized M6 hex bolts to lock S7-300 modules into a fixed physical position.
This design choice is actually clever for high-vibration maritime or mining applications because it completely eliminates module walking along the rail axis. Don’t underestimate the necessity of a solid grounding connection here; the anodized finish on aluminum can act as an insulator. To comply with IEC 61131-2 grounding standards, you must use a serrated washer under your main PE (Protective Earth) grounding bolt to scratch through the oxide layer directly into the bare metal profile. Review the spacing requirements in the Siemens installation manual (Doc Reference: A5E00105492) to leave adequate clearance above and below the rail for proper thermal convection before drilling your backpanel layout.
