Cable tray CF 30/100, 30x100mm, stainless steel 304L, E90 system /3m/ CM000028

Application in Harsh Environmental Conditions

The cable tray with dimensions 30x100 mm, made of stainless steel 304L (1.4301), is a solution dedicated to installations requiring resistance to corrosion and aggressive atmospheric factors. Thanks to the use of 304L grade material and the surface pickling and passivation process, the product maintains its mechanical and aesthetic properties in temperatures ranging from -20 °C to 120 °C. This is a key feature for industrial facilities, cold storage rooms, swimming pools, or coastal zones where standard galvanized steel would quickly degrade. The "U"-shaped profile with a length of 3 meters provides a rigid load-bearing structure that does not require additional painting or maintenance during operation.

Construction and Installation Capabilities

The tray mesh has been designed to facilitate cable ventilation and rapid cable installation without the need for complex tools. The useful cross-section of 2643 mm² allows for routing a significant number of conductors in a single circuit, which is important when modernizing existing distribution cabinets or laying new cable routes. The absence of built-in partitions gives the installer full freedom in organizing space – it can be freely modified or left open for better cable cooling. The self-weight of approximately 0.52 kg/m makes the element lightweight, facilitating its transport and installation on brackets or ceiling supports without the need for heavy mounting systems.

Benefits for Installation and Operation

Choosing this model directly translates into reduced long-term infrastructure maintenance costs. The passivated surface of stainless steel creates a natural barrier against rust, eliminating the risk of cable contamination by metal corrosion products.

• Thermal Resistance: Operating range from -20 to +120 °C allows use in zones with extreme temperature fluctuations without loss of structural strength.
• System Flexibility: The partition-free profile enables easy addition of new cables at any time without the need to replace the entire cable routing system.
• Ease of Cleaning: The smooth, passivated surface does not trap dust or dirt, which is important in facilities requiring hygiene (e.g., food or pharmaceutical industries).
• Compatibility: This system works perfectly with other Legrand Cablofil mounting components made from appropriate stainless steel alloys.

Key construction parameters influence product selection: the material is stainless steel 304L (1.4301), guaranteeing high chemical and corrosion resistance. Dimensions of 30 mm height by 100 mm width provide an optimal ratio for medium cross-section cables, while the standard length of 3000 mm facilitates route planning without excessive waste. High cable capacity while maintaining lightweight construction results from a useful cross-section of 2643 mm². Natural corrosion protection without additional paint coatings is the result of the surface pickling and passivation process.

It should be noted that this product does not possess a fire integrity maintenance certificate (E90), therefore it should be used in locations where this is not a normative requirement for the given fire zone. For installations requiring fire protection, other solutions with appropriate fire classification should be considered.
