Rittal 9666400 NH fuse-switch disconnector module - 1 WU 3 U

Feature → Business Impact → Application: The SV NH fuse-switch disconnector module accommodates NH disconnectors on mounting plates, enabling a compact, modular configuration that saves space in panel design and reduces risk of misalignment during assembly. This translates to faster installation and lower commissioning time in industrial control panels. Application: RiLine-based switchgear where space optimization is critical and mounting plate assemblies require a dedicated ISV module. Feature → Business Impact → Application: The cover is prepared for a lead seal, which enhances security and traceability in regulated environments, reducing tamper risk and simplifying compliance audits. Application: Electrical infrastructure deployments requiring sealed enclosures for critical disconnect points. Feature → Business Impact → Application: Dimensions of 250 mm width by 450 mm height (1 WU x 3 U) guarantee predictable cabinet fit and standardized module stacking, improving BOM accuracy and procurement efficiency. Application: New builds and retrofits of medium-size switchgear housings. Feature → Business Impact → Application: Material composition (Polystyrene cover with sheet steel cross member) delivers a balance of impact resistance and ease of accessory mounting, lowering total cost of ownership through durable yet serviceable components. Application: Maintenance-heavy environments where panel accessibility is a priority. Feature → Business Impact → Application: Assembly instructions address cross-member compatibility for multiple NH disconnectors (2 x size 2 or 1 x size 3), reducing installation errors and accelerating field assembly. Application: Projects using 9344 series disconnectors with 9666.420 cross-member and 9666.060 hazard protection module. Feature → Business Impact → Application: Weight per pack at 1.08 kg and packs per unit simplify logistics planning, stocking, and line-side replenishment for spare parts. Application: Assembly lines and service depots needing predictable inventory turns. These features collectively support efficiency gains, safer installations, and better lifecycle management for Rittal enclosure ecosystems.
