Product description
SV NH fuse-switch disconnector module (ISV), 1 WU (250 mm), 2 U (300 mm), for 2 x size 00
Lead-seal ready cover provides tamper-evident security for critical circuits. This feature reduces the risk of unauthorized access and simplifies regulatory audits, improving compliance and minimizing rework. It is particularly beneficial in RiLine NH fuse-switch disconnector installations where traceability matters. With a 1 WU x 2U footprint (250 mm x 300 mm), the module fits compact control panels while accommodating 2 x size 00 disconnectors. This sizing improves panel density, shortens wiring runs, and supports scalable expansion in evolving electrical infrastructure. Applications include distribution boards and cabinet-level protection systems. The enclosure uses a polystyrene cover and a sheet-steel cross member finished in RAL 7035, delivering lightweight handling with the rigidity needed for reliable mounting. The standard color aids in visual consistency in control rooms. Assembly guidance notes that when using NH fuse-switch disconnectors of 2 x size 2 or 1 x size 3, cross-member 9666.420 and contact hazard protection module 9666.060 should be added to form a complete module unit. This reduces guesswork during installation and ensures compliant, safe operation. It also aligns with RiLine mounting plate practices for future spare parts compatibility. Packs of 1 piece at 0.84 kg per pack support predictable logistics and minimal freight impact, making stocking easier for distributors and maintenance teams. The material mix and modular design translate to lower total cost of ownership through faster assembly and fewer field errors.

FAQs
The SV 9666.380 is designed to fit RiLine NH fuse-switch disconnector mounting plate assemblies. It supports two x size 00 disconnectors in a 1 WU by 2 U footprint (250 mm wide, 300 mm high) and uses a cover prepared for a lead seal, enabling tamper evidence and regulatory traceability in distribution panels. This makes it suitable for compact control cabinets where space efficiency and safety are priorities.
Install the SV 9666.380 by mounting it on the RiLine mounting plate designed for NH disconnectors. If using NH fuse-switch disconnectors 2 x size 2 or 1 x size 3, add cross-member 9666.420 and the contact hazard protection module 9666.060 to form the complete module unit. Ensure the cover is lead-seal ready and align with the 9344.000 model references for proper fit and compliance during commissioning.
The module has a width of 250 mm and a height of 300 mm, configured as 1 WU x 2 U. It is packaged as 1 piece per pack with a weight of 0.84 kg per pack. These dimensions support compact installation in distribution cabinets while maintaining space for wiring and connectors, contributing to efficient panel design and inventory planning.
Yes. The SV 9666.380 features a lead-seal ready cover, enabling tamper-evident closure for secure, auditable operation in electrical distribution boards. This feature is particularly valuable in environments with stringent access control and regulatory requirements. When assembling, ensure the lead-seal process aligns with panel procedures and any applicable manufacturer recommendations.
This module is compatible with RiLine NH fuse-switch disconnector configurations and is designed to mount on RiLine mounting plates for 2 x size 00 disconnectors. It supports the 1 WU x 2 U footprint (250 mm x 300 mm) and references Model No. 9344.000 for fitting. Always confirm compatibility with your RiLine kit and follow RiLine assembly guidelines for safe, compliant installation.
