Enclosure touch protection module Rittal SV 9666.020, white polystyrol housing, 250×450 mm

Rittal SV 9666.020 is a touch protection module supplied in a white polystyrol housing sized to fit an opening of 250 × 450 mm. Intended for installation in electrical enclosures such as control cabinets, distribution boxes and industrial panels, the module provides a physical barrier to help prevent accidental contact with live parts while maintaining accessibility for authorized personnel.

Advantages

The polystyrol construction offers a smooth, non-conductive surface that is resistant to common impacts and suitable for indoor electrical environments. The standardized footprint of 250 × 450 mm enables straightforward replacement or retrofitting into enclosures with matching cutouts. As a manufacturer-approved accessory, the module is designed to integrate with typical enclosure layouts and reduce the risk of inadvertent contact with energized components.

Suitable for

• Control cabinets and switchgear where a protective barrier is required
• Distribution boxes and electrical panels with a 250 × 450 mm opening
• Industrial applications needing a non-conductive touch protection element

When it may not be suitable

The module is intended for indoor electrical enclosures and may not be appropriate for outdoor installations where prolonged UV exposure, extreme temperatures or direct weathering are factors unless additional environmental protection is provided. It is not a substitute for full electrical isolation or for applications requiring specific fire-retardant or chemical-resistant materials beyond standard polystyrol performance.

Key specifications

• Material: polystyrol (white)
• Nominal cutout / module size: 250 × 450 mm (width × height)
• Function: touch protection for enclosure openings
• Intended use: indoor electrical enclosures such as control cabinets, distribution boxes, industrial panels

How to use

Install the touch protection module into the enclosure cutout sized 250 × 450 mm following the enclosure manufacturer’s mounting guidelines. Ensure the housing seats securely and that any screws or fastening elements used are suitable for the enclosure material. Verify that the module provides the required separation from live parts and that any door or panel operation is not obstructed. Perform a functional inspection after assembly to confirm safe access and protection.

What to consider before purchase

• Confirm the enclosure has a matching 250 × 450 mm cutout or that the cutout can be adapted for this module
• Verify that polystyrol material properties meet your specific environmental and safety requirements
• Check compatibility with the enclosure manufacturer’s mounting system and available internal clearances

Usage recommendations

Use the module as part of an overall safety strategy: combine with appropriate signage, lockout procedures and installation by qualified personnel. For outdoor or harsh environments, consider additional protective measures or alternative materials specified for those conditions.
