Enclosure frame Rittal SV 9666.680 — grey polystyrol housing, width 250 mm, height 300 mm

Rittal SV 9666.680 is a compact enclosure/extension frame made of grey polystyrol, designed to create raised frame sections or to house electrical components in space-constrained installations. With a width of 250 mm and a height of 300 mm, this single-unit frame provides a neat, consistent interface for mounting modules, terminal blocks or small control elements inside control cabinets and equipment housings.

Advantages

The polystyrol construction delivers a lightweight yet dimensionally stable frame with a uniform grey finish suitable for industrial environments. Its defined width and height allow predictable planning and modular extension of cabinet interiors. Supplied as a single unit, the frame simplifies procurement and installation for small adjustments or upgrades to existing enclosures.

Suitable for

• Creating raised sections within control cabinets and electrical enclosures
• Mounting terminal blocks, small control modules, or monitoring devices
• Retrofitting or extending existing cabinet interiors where space is limited
• Applications requiring a consistent aesthetic and uniform mounting surface

When it may not be suitable

This frame is made of polystyrol and is intended for indoor cabinet use; it is not suitable for direct outdoor exposure, high-impact environments, or applications requiring reinforced metal enclosures. For very large equipment layouts or where specialist EMC, fire-resistance or heavy mechanical protection is required, a different enclosure type should be considered.

Key specifications

• Material: polystyrol (grey)
• Width: 250 mm
• Height: 300 mm
• Unit: supplied as a single frame element

How to use

Position the frame at the desired location inside the control cabinet or equipment housing and fasten according to the cabinet manufacturer's instructions or existing mounting points. Use appropriate fasteners and ensure proper alignment with adjacent panels or frames before securing. After installation, mount the required electrical components or modules inside the frame, observing clearance and wiring routes to maintain serviceability and ventilation.

What to consider before purchase

• Verify internal cabinet dimensions and available mounting space to ensure the 250 mm x 300 mm frame fits as intended
• Confirm material suitability for the intended environment (indoor use, moderate mechanical stress)
• Check compatibility with existing mounting profiles, panels or accessories in your cabinet system

Usage recommendations

For reliable results, install the frame on a flat surface within the cabinet and use recommended fastening hardware. Maintain sufficient clearance for wiring and ventilation, and avoid exposure to direct weathering or strong chemical agents that may affect polystyrol.
