Rittal SV 9674.438 fibreglass housing, grey — electrical enclosure component

Rittal SV 9674.438 fibreglass housing, grey is a single-piece fibreglass enclosure component designed for electrical and industrial installations. The component provides dielectric insulation and mechanical protection for mounted equipment and can be used as a replacement or retrofit part in control cabinets as well as in indoor and sheltered outdoor installations. Supplied as one unit per pack, the grey fibreglass construction resists corrosion and supports long-term service in environments where non-metallic housings are preferred.

Advantages

The fibreglass construction offers a combination of electrical insulation and mechanical strength while remaining lightweight compared with many metal alternatives. Its grey finish provides a neutral appearance that integrates with standard control cabinet interiors. Because it is non-metallic, the housing reduces the risk of galvanic corrosion and can simplify grounding requirements in some applications. Supplied as a single unit, it is ready for direct mounting or integration into existing assemblies.

Suitable for

• Protecting electrical components inside control cabinets
• Retrofit or replacement in industrial enclosures
• Indoor and sheltered outdoor installations where fibreglass is acceptable
• Applications requiring dielectric insulation and corrosion resistance

When it may not be suitable

This fibreglass housing is not intended for use as a standalone weatherproof cabinet in fully exposed outdoor environments unless additional sealing and protection measures are applied. It may not be suitable where metal housings are required for electromagnetic shielding or for applications demanding specific mechanical ratings beyond the component's inherent strength.

Key specifications

• Material: fibreglass
• Colour: grey
• Quantity: 1 piece per pack
• Intended use: housing / enclosure component for electrical installations

How to use

Install the fibreglass housing according to the enclosure manufacturer’s mounting instructions or the existing cabinet layout. Ensure compatible fasteners and mounting points are used to achieve secure fixation. Verify that the housing orientation and clearances meet the requirements of the mounted equipment and that any cable entries, gaskets or seals in the surrounding enclosure are compatible with fibreglass surfaces. Check dielectric isolation and grounding practices relevant to the overall assembly before energising equipment.

What to consider before purchase

• Confirm mechanical dimensions and mounting compatibility with your cabinet or assembly
• Assess whether fibreglass material meets environmental and fire-rating requirements for your application
• Determine if additional sealing or shielding is required for outdoor exposure or EMI-sensitive equipment

Usage recommendations

Use corrosion-resistant fasteners and compatible sealants when integrating the fibreglass housing into metal cabinets; perform a functional check of electrical isolation and mounting stability before placing equipment into service.
