Quick Summary
Rittal 9677521 SV System Attachment enables secure busbar mounting inside VX enclosures. Engineers often struggle with precise depth adjustment and alignment during panel wiring; this accessory provides fixed left/right attachments and adjustable punched sections to streamline installation. It aligns with ETIM 9 EC001900 and ECLASS 8.0 27400613 for cross-system compatibility, and the PCF notes support lifecycle planning through a transparent environmental profile. Designed for 185 mm center-to-center spacing, it delivers faster assembly, repeatable layouts, and a lower total cost of ownership when deploying busbar systems in 800 mm VX enclosures. This translates to reduced field rework and improved uptime across electrical distribution panels.

Product description
SV system attachment for VX (W: 800 mm), for busbar holder SV 9677500
Feature is a SV system attachment for VX enclosures designed to attach busbar systems with 185 mm centre-to-centre spacing. Business impact includes faster installation, repeatable layouts, and reduced commissioning risk, enabling engineers to deploy more panels per shift. In practice, the left/right system attachments and punched sections without mounting flanges simplify initial alignment and later field servicing, improving maintenance uptime. The application is specifically for VX enclosures with an 800 mm width, leveraging busbar holder SV 9677500 for a robust, modular solution. Compatibility with sheet steel construction and zinc-plated finish ensures corrosion resistance in industrial settings, delivering longer service life and lower replacement costs. Depth-adjustment capability via the 23 x 64 mm punched section supports variable enclosure depths, reducing custom fabrication time and supporting standardized assembly workflows. The packaged design (1 pack) weighs 3.74 kg and includes complete assembly parts, enabling predictable installation planning and streamlined procurement for panel builders.

FAQs
SV 9677.521 is designed for VX enclosures with a width of 800 mm and supports 185 mm centre-to-centre busbar spacing. It ships with two system attachments (left/right), two punched sections without mounting flanges, and the necessary assembly parts, enabling a straightforward retrofit or new install without fabricating mounting panels.
Key specs include sheet steel material with a zinc-plated surface finish, a pack size of 1, weight 3.74 kg per pack, and compatibility with the SV 9677500 busbar holder. It also contains assembly instructions for depth adjustment and includes two punched sections for inner mounting levels, making it suitable for variable-depth VX installations.
Yes. SV 9677.521 is intended for use with the SV 9677500 busbar holder inside VX enclosures, supporting 185 mm centre-to-centre spacing and ensuring a stable, repeatable mounting solution for modular busbar configurations.
SV 9677.521 references ETIM 9 EC001900 and ECLASS 8.0 27400613 for cross-system classification, and notes on PCF category indicate a Category B cradle-to-gate footprint. This supports consistent procurement data and lifecycle assessment across engineering teams.
Using SV 9677.521 reduces installation time through standardized parts and depth-adjustment capability, lowers field rework, and provides a predictable CO2 impact (14.2 kg CO2 eq per pack, Cat B). The result is lower maintenance costs and higher panel reliability over the life of VX-based electrical distributions.
