Enclosure housing Rittal SV 9666.590 polystyrol grey, width 250 mm, height 300 mm

Rittal SV 9666.590 is a grey enclosure housing made of polystyrol with external dimensions of 250 mm width and 300 mm height. Supplied as a single unit, this enclosure provides a protective housing for electrical and electronic components in control cabinets, wall-mounted installations, or small machine housings. The polystyrol construction offers a rigid, electrically insulating shell suitable for basic mechanical protection and internal module mounting.

Advantages

The enclosure combines a compact footprint with straightforward mounting options, making it practical for installations where space is limited. Its polystyrol material provides electrical insulation and dimensional stability under typical indoor conditions. The neutral grey finish supports unobtrusive integration into control panels and industrial interiors while allowing easy identification of mounted modules and cable entry points.

Suitable for

• Housing small control electronics or terminal blocks in control cabinets
• Wall-mounted or panel-mounted installations in industrial or commercial environments
• Prototyping and retrofit projects where a prefabricated enclosure is needed
• Organizing and protecting wiring and internal modules with limited space requirements

When it may not be suitable

This enclosure is intended for basic mechanical protection and internal organization; it is not designed for heavy-duty environmental protection, such as outdoor exposure to rain, high humidity, or corrosive atmospheres unless additional sealing and protection measures are applied. It is also not specified for applications requiring high-impact resistance, high-temperature operation beyond typical indoor ranges, or verified ingress protection ratings for dust and water.

Key specifications

• Material: polystyrol (rigid, electrically insulating)
• Colour: grey
• Width: 250 mm
• Height: 300 mm
• Supply format: single unit (housing only)

How to use

Mount the enclosure in the desired location following local electrical and mounting regulations. Prepare internal components and DIN-rail or panel-mount fixtures as required before insertion. Ensure secure fastening of internal modules and route cables through intended entry points or knockouts; if cable glands or grommets are required, select compatible sizes and install them prior to final assembly. Verify that the enclosure provides adequate clearance for heat dissipation of internal components and that all earth/ground connections are made where necessary.

What to consider before purchase

• Confirm internal mounting requirements (DIN rail, mounting plate, or custom brackets) and available internal space for components.
• Check environmental requirements: indoor use vs. need for IP-rated protection or UV resistance.
• Verify compatibility of cable entry points and the need for additional seals, glands, or ventilation.
• Ensure material properties (polystyrol) meet mechanical and electrical insulation needs for your application.

Usage recommendations

Install the housing on stable surfaces and avoid direct outdoor exposure unless additional sealing is applied. Use appropriate cable glands and secure internal modules to prevent movement. For applications with higher environmental demands, consider enclosures with defined ingress protection or different material properties.
