Product description
SV Support rail module (ISV), 3 WU (750 mm), 3 U (450 mm), 3 support rails
Feature → Business Impact → Application: The SV 9666.223 provides three 25 mm pitch rails on a 750 mm by 450 mm footprint, enabling precise positioning of terminal blocks and switchgear. This translates to faster assembly, fewer misplacements, and improved workspace utilization in 19 inch cabinets. Application: Ideal for control panels and distribution enclosures where space planning and component organization are critical for performance and serviceability. Feature → Business Impact → Application: The support rails are sheet steel, zinc-plated, offering robust mechanical support and long-term corrosion resistance in harsh environments. This reduces maintenance intervals and ensures consistent electrical containment in industrial automation setups. Feature → Business Impact → Application: The cover is polystyrene and is prepared for a lead seal, enabling tamper-evident protection and compliance with stricter industry security requirements. Application: Suitable for plants where tamper resistance and seal integrity are important for audits and safety. Feature → Business Impact → Application: The product includes assembly parts and is designed for compatibility with standard 35/15 mm rails, simplifying retrofits and new installations alike. Application: Works smoothly with a wide range of terminal blocks, switchgear, and ancillary components in enclosure interiors. Feature → Business Impact → Application: The 3 WU / 3 U configuration supports modular expansion, allowing incremental capacity increases as control systems evolve. Application: Useful for scalable automation projects, machine dashboards, and process control cabinets. Feature → Business Impact → Application: Color and material consistency (RAL 7035, polystyrene cover) ensures uniform appearance and predictable thermal and flame behavior in enclosures. Application: Applies to OEM equipment housings and service cabinets where aesthetic and safety standards matter. Feature → Business Impact → Application: The product’s density (4 kg per pack) and pack-efficient design enable straightforward logistics and reduced warehousing footprint. Application: Beneficial for procurement planning and just-in-time assembly in distributed manufacturing environments.

FAQs
SV 9666.223 is designed for Rittal enclosures and standard 35/15 mm rail systems, featuring three adjustable 25 mm pitch rails within a 750 mm by 450 mm footprint. Includes assembly parts for straightforward integration with terminal blocks and switchgear, minimizing on-site adaptation and downtime.
The 25 mm pitch adjustment allows precise spacing between installed components, reducing crowding and enabling clean cable routing. This improves thermal management, simplifies verification during audits, and supports scalable configurations for evolving control architectures without rework.
Yes. The cover is prepared for a lead seal, enabling tamper-evident installations within standard enclosure configurations. This is advantageous for security-conscious environments and regulated facilities where seal integrity and traceability are required.
The SV 9666.223 aligns with classification standards such as ETIM 9 EC002525 and ECLASS 8.0 27142411, and carries an EAN for traceability. While CE/IP considerations are typical in enclosure applications, always verify site-specific regulatory requirements and supplier certifications to ensure full compliance.
The pre-configured rails, lead-seal-ready cover, and included assembly parts reduce installation time and field engineering effort. The modular 3 WU / 3 U design supports incremental capacity, lowering upfront costs and enabling staged automation rollouts with predictable maintenance and long-term ownership value.
