Enclosure cover Rittal SV 9674.380 — PVC housing, black, single-piece

Rittal SV 9674.380 is a black enclosure cover made of polyvinyl chloride (PVC), supplied as a single-piece housing component. Designed for use in electrical distribution and switchgear assemblies, this cover provides a protective insulation layer to conceal and shield distribution rails and busbar systems from accidental contact and dust ingress in industrial environments.

Advantages

The PVC construction offers electrical insulation and chemical resistance appropriate for many indoor industrial settings. Its single-piece design simplifies installation and reduces the number of joints where dust or moisture could accumulate. The black finish provides a neutral appearance that integrates with standard control cabinet interiors and switchgear panels.

Suitable for

• Covering distribution rails and busbar arrangements inside control cabinets
• Insulating live parts to reduce risk of accidental contact
• Applications where dust protection and basic chemical resistance are required

When it may not be suitable

This PVC enclosure cover is intended for indoor, protected environments; it is not specified for outdoor use where prolonged UV exposure, extreme temperatures, or direct weathering may degrade PVC properties. It also does not replace full IP-rated enclosures where a specific ingress protection level is required by standards or regulations.

Key specifications

• Material: polyvinyl chloride (PVC)
• Colour: black
• Configuration: single-piece cover
• Application area: protective housing for distribution rails and switchgear interiors

How to use

Position the cover over the distribution rail or busbar assembly inside the cabinet or enclosure ensuring correct alignment with mounting features and adjacent components. Secure the cover according to the cabinet or switchgear manufacturer's instructions, avoiding excessive mechanical stress on the PVC. Ensure that any heat-generating components have adequate clearance and ventilation before closing the panel.

What to consider before purchase

• Compatibility with the dimensions and mounting method of your distribution rails or busbar system
• Suitability for the intended environment (indoor use, temperature range, and exposure to chemicals or UV)
• Whether a specific ingress protection (IP) rating or fire performance class is required for your installation

Usage recommendations

Inspect the cover for damage before installation, and verify that it does not obstruct required cooling or maintenance access. For installations that demand higher mechanical strength, flame retardancy, or outdoor resistance, consult the system documentation or select an enclosure component specified for those conditions.
