Why Choose the Mersen BB1-2COV Protective Fuse Cover?
The Mersen BB1-2COV is a dedicated touch-protection cover for NH size 1 and size 2 fuse-links installed in compatible open fuse-base assemblies. Also identified by the Mersen item number K214691, this protective accessory covers the fuse-link gripping lugs to help reduce the risk of accidental contact during normal operation.
Designed for use within Mersen NH fuse systems, the BB1-2COV provides an additional insulating barrier around accessible fuse-link tags. Its compact clip-on design allows the cover to be fitted to compatible installations without altering the electrical characteristics of the fuse-link or fuse base.
The BB1-2COV is supplied in a pack of three protective covers, making it particularly suitable for three-phase fuse-base assemblies. Its durable, lightweight construction supports safer switchboard, distribution-panel and industrial control-panel installations.

Additional Touch Protection for NH Fuse Systems
NH fuse-links incorporate gripping lugs that allow them to be inserted and removed using an appropriate insulated fuse handle. In open fuse-base installations, these tags may remain accessible after the fuse-link has been fitted.
The Mersen BB1-2COV clips over the gripping lugs of compatible NH1 and NH2 fuse-links, providing an additional physical barrier against accidental contact. It is a protective accessory and does not replace the fuse base, fuse-link, enclosure or safe isolation procedures required for the electrical installation.
Typical Applications
- NH1 and NH2 fuse-base assemblies.
- Industrial low-voltage switchboards.
- Power-distribution panels.
- Motor control centres.
- Machinery and automation control cabinets.
- Commercial electrical distribution equipment.
- OEM electrical-panel construction.
- Maintenance and retrofit projects requiring additional touch protection.
