SIEMENS 6ES7195-1GA00-0XA0 Profile Rail – Structural Mounting Solution | SIMATIC S7-300 Platform
Engineering Background
The SIMATIC S7-300 series has been a cornerstone of industrial automation for over two decades, deployed across discrete manufacturing, process control, and infrastructure applications worldwide. The mechanical integrity of any S7-300 control cabinet begins with the profile rail — the structural backbone that secures every module in the rack assembly. The 6ES7195-1GA00-0XA0 is the OEM-specified 482.6 mm (19-inch) profile rail engineered exclusively for S7-300 system builds.
Product Positioning
This rail is the standard-length mounting solution for engineers specifying compact to mid-size S7-300 control panels. It accommodates the full range of S7-300 signal, function, and communication modules, and is the preferred choice for 19-inch rack enclosure integration. Procurement engineers sourcing replacement rails, expanding existing installations, or commissioning new panels will find this component essential for maintaining system structural compliance and warranty validity.

- Integrated Grounding: Built-in PE grounding lug supports EMC compliance without additional hardware, reducing BOM complexity.
- Corrosion-Resistant Finish: Anodized aluminum construction withstands industrial environments including humidity, dust, and mild chemical exposure.
- Full Module Range Support: Accepts all S7-300 module types — CPU, SM, FM, CP, IM, PS — on a single rail without adapter hardware.
- Long Service Life: Designed for the operational lifespan of the S7-300 platform; no scheduled replacement interval under normal conditions.
System Architecture & Signal Flow
In an S7-300 rack assembly, the profile rail serves as both the mechanical chassis and the electrical ground reference plane. Modules clip onto the rail via integrated locking mechanisms and interconnect via the backplane bus connector. The rail’s grounding point ties the entire rack to the cabinet PE bus, ensuring a low-impedance ground path for all installed modules. For multi-rack configurations, the rail interfaces with IM (Interface Module) pairs to extend the backplane across up to 4 expansion racks, each requiring its own profile rail of appropriate length.
Recommended rail selection by rack width: 160 mm (up to 2 modules) → 482.6 mm (standard 19-inch, up to 8 modules) → 530 mm / 830 mm / 2000 mm for extended configurations.

Technical FAQ
Q: Can this rail be cut to a shorter length?
A: Siemens does not recommend field-cutting of profile rails as it may compromise the grounding integrity and module alignment. Select the appropriate standard length for your application.
Q: Is this rail compatible with S7-400 or S7-1500 modules?
A: No. The 6ES7195-1GA00-0XA0 is designed exclusively for the S7-300 module family. S7-400 and S7-1500 use different rail profiles and dimensions.
Q: How many S7-300 modules can be mounted on this rail?
A: Up to 8 signal/function modules plus 1 CPU and 1 power supply, subject to the total current draw not exceeding the PS module rating.
Q: Does the rail include mounting screws?
A: The rail itself does not include panel mounting screws. M6 screws with appropriate length for your enclosure panel thickness are required and sourced separately.
Q: What is the difference between 6ES7195-1GA00-0XA0 and other S7-300 rail lengths?
A: The -1GA00- designation indicates the 482.6 mm (19-inch) length. Other variants include -1BE00- (160 mm), -1GF00- (530 mm), -1GG00- (830 mm), and -1GH00- (2000 mm).
