Enclosure module Rittal SV 9666.240 — polystyrene housing, white, 250×150 mm

Rittal SV 9666.240 is a lightweight enclosure module with a white polystyrene housing designed for mounting electrical and electronic components. The compact unit measures 250 × 150 mm and is supplied as a single-piece housing suitable for control panels, instrument mounting and small device enclosures where a non-metallic, insulating case is required.

Advantages

The polystyrene construction provides electrical insulation while keeping the housing lightweight and easy to handle. Its plain white finish allows for simple marking, labelling or painting to match installation requirements. The single-piece design simplifies assembly and reduces installation time compared with multi-part enclosures. Compatibility with standard instrument and control panel mounting makes it convenient for small installations and quick replacements.

Suitable for

• Control panel sections and small instrument housings
• Mounting of PCBs, small relays, terminal blocks and miniature controllers
• Prototyping and low-load electronic assemblies that require non-metallic housings
• Lightweight fixed installations where corrosion-resistant material is preferred

When it may not be suitable

This polystyrene enclosure is not intended for heavy mechanical loads, high-impact environments or applications requiring significant mechanical protection. It is also not suitable where metal shielding or high thermal dissipation is required; metallic enclosures or ventilated designs should be chosen for electromagnetic shielding or heat-intensive components.

Key specifications

• Material: Polystyrene (white)
• External dimensions: 250 mm (width) × 150 mm (height)
• Configuration: Single-piece enclosure module
• Colour: White
• Intended use: Mounting electrical or electronic components in control panels and small devices

How to use

Mount the enclosure in the panel or fixture location that matches its 250 × 150 mm footprint, verify secure seating and fixation using suitable screws or clips according to the installation setup. Prepare internal component mounting by marking and machining or drilling the housing where necessary for cable entries, connectors or mounting standoffs. Place PCBs, terminal blocks or small devices inside, secure them with appropriate fasteners or adhesive supports, and make required wiring connections while observing insulation and clearance requirements. After assembly, close any openings and perform a functional check of the mounted components.

What to consider before purchase

• Confirm the internal space and mounting options suit the size and number of components to be installed
• Assess mechanical load, impact resistance and requirement for electromagnetic shielding
• Check environmental conditions (temperature, humidity, chemical exposure) to ensure polystyrene is acceptable
• Plan for cable entry, connector access and any necessary cutouts prior to installation

Usage recommendations

For general-purpose control panel and instrument mounting, use this Rittal polystyrene module where electrical insulation, lightweight construction and easy modification are priorities. Avoid exposure to solvents or high temperatures and provide additional mechanical protection or shielding where required.
