The Rittal HD system enclosure is a robust housing made of stainless steel, designed for use in demanding industrial environments. With dimensions of 1,200 mm (width) × 1,800 mm (height) × 500 mm (depth), it provides sufficient space for mounting electrical and electronic components. The enclosure is designed with two doors and includes a mounting plate as well as a screwed-in center brace, which facilitates the installation of devices and control panels. The door hinges are standardly arranged on the right, but can be changed to the left, enabling flexible use at different locations.

Applications
This enclosure is suitable for use in production plants, process automation, the food industry, and environments with high requirements for hygiene and corrosion resistance. The use of stainless steel 1.4301 (AISI 304) for the housing and doors, and stainless steel 1.4404 (AISI 316L) for the lock insert, ensures high resistance to moisture, chemical influences, and mechanical stress. The silicone seal, compliant with FDA regulation 21 CFR 177.2600, is suitable for applications in the food industry and prevents the ingress of dirt or liquids.

Functions and Equipment in Detail
The housing and doors feature a brushed surface with a grit of 400 and a roughness depth under 0.8 μm, providing a clean, easy-to-clean surface. The mounting plate is galvanized and offers a stable base for securing components. The door opens to an angle of 125°, ensuring good access to the interior. The enclosure is supplied with a welded rear wall base plate, which increases stability and enables secure mounting.

Technology Explained Simply
The enclosure meets protection class IP 66 and IP X9 according to IEC 60 529, meaning it is dust-tight and protected against strong water spray and short-term immersion. Protection class NEMA 4X and Type ratings according to UL 50E (Type 1, Type 3R, Type 4X, Type 12) confirm suitability for outdoor use as well as in damp or corrosive environments. The IK code IK08 indicates that the enclosure is protected against mechanical impacts such as shocks or vibrations up to a certain intensity. The use of stainless steel 1.4301 (AISI 304) as the base material ensures high corrosion resistance and durability.

Compatibility and Accessories
In addition to the standard delivery scope, an optional HD base frame with levelling is available, enabling secure and level installation of the enclosure. The mounting plate has dimensions of 1,099 mm (width) × 1,696 mm (height) and is designed for securing devices and control panels. The use of stainless steel and silicone seals allows compatibility with other components from the Rittal HD system, which are also designed for high requirements regarding hygiene and corrosion resistance.

Installation and Mounting
Installation is carried out via the pre-mounted mounting plate and the screwed-in center brace. The doors are already fitted with seals and can be mounted on the left or right side as required. The robust stainless steel construction and integrated base plate facilitate installation and ensure stable anchoring. During installation, a level surface must be ensured to guarantee the function of the seal and the protection rating.

Advantages in Operation
The enclosure offers high mechanical and chemical resistance, making it suitable for use in harsh industrial environments. The clean surface and FDA-compliant seal facilitate cleaning and maintenance, especially in the food industry. Protection classes IP 66, IP X9, NEMA 4X, and UL Type ratings ensure reliable protection against environmental influences. The modular construction allows flexible adaptation to different requirements, with options such as the HD base frame further supporting installation.
