Enclosure accessory Rittal SV 9666.603 polystyrol housing, grey, width 750 mm, height 300 mm

Rittal SV 9666.603 is a polystyrol housing accessory designed for electrical enclosures and control cabinets. The grey, non-metallic housing provides a compact, lightweight mounting space with a width of 750 mm and height of 300 mm. Supplied as a single unit, it is intended for integration of components where a plastic enclosure is preferred for electrical isolation, reduced weight, or corrosion resistance.

Advantages

This polystyrol housing offers a low-weight alternative to metal enclosures and provides electrical insulation between mounted components and the surrounding cabinet. Its compact dimensions (750 mm x 300 mm) make it suitable for situations where space is limited. The neutral grey finish is compatible with standard control cabinet interiors and supports tidy, professional installations.

Suitable for

• Mounting small to medium electrical components inside control cabinets
• Applications requiring non-metallic housings for electrical insulation
• Environments where reduced weight or corrosion resistance is desirable
• Retrofit or new installations with a requirement for a 750 mm wide by 300 mm high housing

When it may not be suitable

The polystyrol housing is not suited for applications that require mechanical protection against high-impact forces or heavy external loads; a metal enclosure would be more appropriate in such cases. It is also not intended for use as a load-bearing structural element or in locations where high-temperature resistance beyond standard plastomer limits is required.

Key specifications

• Material: polystyrol (plastic)
• Colour: grey
• Width: 750 mm
• Height: 300 mm
• Packaging: single unit (1 pc)

How to use

Install the housing inside the control cabinet according to cabinet layout and component arrangement. Ensure the mounting surface is clean and compatible with plastic fasteners or brackets. Position and secure the housing so that internal components have adequate clearance and ventilation. Route wiring and cables through designated entries or cut-outs, and secure cables with appropriate clamps to prevent strain on terminals. Follow general electrical safety practices and any applicable installation standards.

What to consider before purchase

• Verify internal dimensions and mounting space required for your components
• Confirm that polystyrol material meets the insulation and temperature requirements of your application
• Check compatibility with existing cabinet mounting points and fasteners
• Assess whether additional gaskets or seals are needed for environmental protection

Usage recommendations

Use the Rittal polystyrol housing for non-load-bearing component mounting where electrical insulation and reduced weight are priorities. Avoid exposure to strong solvents or excessive heat, and secure wiring to maintain safe operation within the enclosure.
