Rittal SV 9666.665 blind cover for NH fuse switch size 00, grey, width 117 mm

Rittal SV 9666.665 blind cover is a grey protective accessory designed for NH fuse switches size 00 with a nominal width of 117 mm. Supplied as a single piece, this cover fits over NH-trenners to reduce the risk of accidental contact and limit ingress of dust and debris in electrical switchgear and distribution panels. The product is intended to integrate with Rittal switchgear components and offers a compact solution for safeguarding live parts during operation and maintenance.

Advantages

The blind cover provides a simple, durable layer of protection that prevents direct access to fuse switch contacts and minimizes contamination of internal components. Its grey finish blends with standard switchgear enclosures and is manufactured to match the dimensions used for NH fuse switch size 00. The single-piece design allows straightforward installation and removal for inspection or servicing while maintaining a low profile inside distribution cabinets.

Suitable for (tasks / use cases)

• Covering NH fuse switches size 00 in distribution boards and switchgear
• Protecting live parts during maintenance and component replacement
• Reducing ingress of dust and foreign objects in electrical cabinets
• Temporary or permanent installation in industrial and commercial electrical systems

When it may not be suitable

This blind cover is specifically sized for NH fuse switch size 00 and a nominal width of 117 mm; it may not fit other NH sizes or non-standard switchgear dimensions. It is a passive protective accessory and does not provide insulation rated for voltage or current beyond its intended application; for electrical isolation or high-voltage protection, purpose-designed insulating barriers or certified isolation devices should be used.
