Enclosure housing Rittal SV 9666.560 — polystyrene (PS), grey, single-piece

Rittal SV 9666.560 is a grey enclosure housing manufactured from polystyrene (PS) and supplied as a single-piece unit. It is intended for use in electrical and control cabinet installations where a lightweight, non-metallic housing is preferred. The housing provides mechanical protection for internal components and contributes to a tidy, uniform installation appearance while being compatible with NH slimline fuse-switch disconnectors in sizes 00 to 3 (100/185 mm bar centre distance).

Advantages

The polystyrene construction offers a lightweight solution that is easy to handle and install, reducing mounting effort compared with heavier metal enclosures. The grey finish gives a neutral, professional look suitable for a variety of technical environments. As a single-piece housing, it simplifies assembly and minimizes gaps where dust or debris could enter, helping to protect internal components.

Suitable for

• Housing NH slimline fuse-switch disconnectors, sizes 00 to 3 (100/185 mm bar centre distance)
• Lightweight control cabinets and electrical assemblies where non-metallic enclosures are required
• Applications needing a neat, uniform external appearance for installed components

When it may not be suitable

This polystyrene enclosure is not intended for environments requiring robust impact resistance or high mechanical load capacity typical of metal enclosures. It may not be appropriate where high temperatures, aggressive chemicals, or UV exposure are present for prolonged periods, unless additional protective measures are taken.

Key specifications

• Material: Polystyrene (PS)
• Colour: Grey
• Unit count: Single-piece housing
• Compatibility: Designed for NH slimline fuse-switch disconnectors, sizes 00 to 3 (100/185 mm bar centre distance)

How to use

Install the enclosure housing onto the mounting surface or within the control cabinet according to the project layout and compatible device spacing. Place the NH slimline fuse-switch disconnectors into the housing, aligning them to the specified bar centre distance (100/185 mm) and secure following the disconnectors’ installation instructions. Ensure cable entries and internal wiring are routed to avoid strain on terminals and to maintain clearances required for safe operation. Verify fit and alignment before final tightening.

What to consider before purchase

• Confirm compatibility with the specific NH slimline fuse-switch disconnector sizes used in your installation (00 to 3) and the 100/185 mm bar centre distance.
• Assess the operating environment for temperature extremes, chemical exposure, or UV light that could affect polystyrene performance.
• Check mechanical protection requirements; choose a metal enclosure if higher impact resistance or mechanical strength is necessary.

Usage recommendations

For safe and durable installation, use this housing in indoor electrical cabinets with controlled ambient conditions, avoid direct sunlight and sources of heat, and follow the fuse-switch disconnectors’ manufacturer installation instructions. Regular visual inspections and proper cable management will help maintain protection and appearance over time.
