FAQs
Begin by verifying the enclosure footprint (500 mm x 300 mm) and prepare the mounting plate assembly for NH disconnectors. Use the 2 WU x 2 U configuration and 4 x Gr. 00 devices as specified. Install the cross-member 9666.420 and contact hazard protection module 9666.060 to ensure safe, compliant operation before sealing the cover to enable lead seal readiness.
The SV 9666.390 module has a width of 500 mm and height of 300 mm, configured as 2 WU and 2 U. It is designed to fit 4 x Gr. 00 fuse elements and accommodates RiLine NH fuse-disconnectors on mounting plates. It pairs with Model No. 9344.000 and is supplied as a 1-piece pack with a weight of 1.6 kg.
Yes, the cover is prepared for a lead seal. This enables tamper-evident security for critical switchgear assemblies and supports compliance in regulated environments. Lead-seal readiness reduces rework during audits and ensures that any access or modifications are traceable to a specific maintenance window or operator.
The cover is made from polystyrene while the cross member uses sheet steel, delivering a robust yet lightweight structure. The colour is specified as RAL 7035, ensuring visual consistency across modular control panels and compatibility with standard industrial enclosures.
Follow the recommended assembly sequence: use the NH fuse-switch disconnector 2 x size 2 or 1 x size 3 per the data, attach the cross-member 9666.420 and the contact hazard protection module 9666.060 to form a secure module unit, then mount on a suitable RiLine NH frame. Ensure the module is compatible with Model No. 9344.000 and confirm 4 x Gr. 00 configuration before sealing.
