Mounting Profile Rittal CP 6660.050 — Stainless Steel CP 40 Closed

Rittal CP 6660.050 is a closed CP 40 mounting profile made of stainless steel, designed to provide a durable and corrosion-resistant support structure inside enclosures and control cabinets. The profile is intended for mounting rails, brackets, terminal blocks and other electrical or automation components where a robust, long-lasting support is required. Its stainless steel finish offers enhanced resistance to environmental factors compared with standard steel profiles, making it suitable for industrial and commercial installations where hygiene or corrosion resistance is important.

Advantages

The closed CP 40 profile delivers consistent mechanical strength and dimensional stability while minimizing exposure of internal cavities to dust and contaminants. Stainless steel construction ensures improved corrosion resistance and a longer service life in demanding environments. The profile’s closed design provides a clean appearance and simplifies mounting of accessories along a standardized cross-section, supporting straightforward integration with existing CP 40-compatible components.

Suitable for

• Mounting DIN rails, terminal blocks and control devices inside enclosures and control cabinets
• Applications requiring corrosion-resistant support structures, such as food processing, pharmaceutical and outdoor installations
• Industrial automation cabinets, switchgear and electrical distribution panels
• Environments where a closed profile is preferred to limit ingress of dust and particles

When it may not be suitable

This stainless steel closed profile may not be the optimal choice where very low-cost or temporary installations are required and where standard galvanized or painted profiles would suffice. It may also be unnecessary when open profiles are specifically needed to provide easier cable routing or direct access to the profile interior for custom modifications.

Key specifications

• Material: stainless steel
• Profile type: closed CP 40 mounting profile
• Surface: stainless finish for corrosion resistance
• Intended use: support for rails, brackets and mounting hardware in enclosures and cabinets

How to use

Measure and mark the required length and mounting points inside the enclosure or cabinet. Secure the profile using appropriate fasteners compatible with the cabinet material and the profile’s stainless steel construction. Attach DIN rails, brackets or other accessories to the CP 40 cross-section following component manufacturer instructions. Ensure electrical continuity and grounding as required by local regulations when integrating the profile with live electrical systems. Cut and finish exposed ends to prevent sharp edges before inserting components.

What to consider before purchase

• Confirm compatibility with existing CP 40 accessories and mounting hardware
• Verify required length and whether on-site cutting is necessary
• Assess environmental conditions to determine if stainless steel is required for corrosion resistance
• Check fastening method and compatibility with the enclosure or cabinet construction

Usage recommendations

For best results, install the profile with appropriate corrosion-resistant fasteners and ensure proper grounding where applicable. When cutting stainless steel, use suitable tools and deburr edges to maintain safety and fit. Regular inspection in corrosive or humid environments will help preserve mechanical integrity and mounting reliability.
