Enclosure Rittal SV 9674.418 fibreglass housing grey, for busbar holders

The Rittal SV 9674.418 fibreglass housing in grey is a non-metallic enclosure designed to protect electrical components and busbar holders in industrial and commercial distribution systems. Made from reinforced fibreglass, the enclosure offers corrosion resistance and electrical insulation while providing a rigid structure for mounting busbar holders and internal assemblies. Its neutral grey finish is suitable for technical rooms and outdoor or indoor installations that require a durable, non-conductive housing.

Advantages

This fibreglass enclosure combines mechanical strength with chemical resistance, reducing the risk of corrosion in humid or corrosive environments. The non-metallic construction provides inherent electrical insulation, which can simplify grounding considerations compared with metallic cabinets. Its design supports standard busbar holders and internal mounting, enabling organized and secure arrangement of distribution components.

Suitable for

• Housing busbar holders and distribution components in electrical distribution panels
• Indoor and sheltered outdoor installations where corrosion resistance is required
• Locations that benefit from non-conductive enclosures for additional electrical isolation
• Industrial, commercial or utility installations requiring robust, lightweight housings

When it may not be suitable

Because the enclosure is non-metallic, it may not provide the same level of mechanical impact resistance or EMI shielding as steel or aluminium cabinets; applications that require strong physical protection or electromagnetic screening should consider metallic alternatives. This fibreglass housing is intended for use with compatible busbar holders and mounting systems; it may not be suitable where bespoke internal fittings or very specific mounting rails are required.

Key specifications

• Material: reinforced fibreglass composite
• Color / finish: grey
• Designed to accommodate busbar holders and electrical components
• Properties: corrosion-resistant, electrically insulating
• Typical use: industrial and commercial electrical distribution enclosures

How to use

Install the enclosure on a suitable flat surface or mounting structure following local electrical codes. Fit compatible busbar holders into the designated mounting points and secure distribution components inside the housing using recommended fasteners. Ensure appropriate cable entry points and sealing are provided for environmental protection, and follow manufacturer instructions for grounding or bonding where applicable despite the enclosure's non-metallic nature. Verify clearances and ventilation requirements for heat-generating components before commissioning.

What to consider before purchase

• Confirm compatibility with the specific busbar holder dimensions and mounting arrangement you plan to use
• Assess environmental exposure (moisture, chemicals, UV) to ensure fibreglass is appropriate
• Determine whether additional shielding or impact protection is required for your application
• Check required cable entry, gland sizes and sealing solutions for your installation

Usage recommendations

Use corrosion-resistant fasteners and appropriate sealing at cable entries. For installations with higher mechanical or EMI protection needs, consider combining this fibreglass housing with internal shielding or choosing a metallic enclosure. Follow all applicable installation standards and Rittal guidance for mounting busbar holders and arranging electrical components.
