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.
