Why Choose the Mersen K222120 DII Touch Protection Ring?
The Mersen K222120 is a dedicated DII touch protection ring designed for use with Mersen D-system fuse equipment. It provides an insulating barrier around the fuse arrangement, helping reduce the risk of accidental contact with accessible conductive components in low voltage electrical distribution installations.
Developed as part of the Mersen D-system ring adapter, fittings and touch protection range, the K222120 is designed to fit compatible DII fuse bases. Its purpose-built construction supports safe, orderly assembly while retaining the straightforward fuse replacement and maintenance associated with traditional screw fuse systems.
The K222120 is supplied in a pack of 50 rings, making it suitable for panel builders, electrical contractors and maintenance departments installing or refurbishing multiple DII fuse positions. Each ring has an approximate product weight of 0.015 kg.

Additional Protection for DII Fuse Systems
D-system fuse equipment is widely used in low voltage distribution boards for protecting cables, power lines and connected equipment. Accessories such as the Mersen K222120 help complete the fuse-base assembly and provide an additional insulating barrier around the installed fuse arrangement.
The ring is particularly useful in installations where fuse links may be replaced during routine maintenance. When correctly fitted with compatible equipment, it supports a safer and more professional DII fuse-system installation.
Typical Applications
- Low voltage electrical distribution boards.
- DII screw fuse-base assemblies.
- Industrial switchboards and control panels.
- Commercial building distribution equipment.
- Electrical panel manufacturing.
- Maintenance and refurbishment of existing D-system installations.
- Infrastructure and utility distribution systems.
