Reliable Protection for Industrial Distribution Systems
The Mersen NH1GG69V224 uses a full-range gG time-current characteristic, allowing it to protect circuits against sustained overloads as well as severe short-circuit faults. It can therefore be used as the principal protective fuse for appropriately rated cables, conductors and general-purpose electrical equipment.
During a high-current fault, the fuse link limits the peak current and the amount of energy passed into the electrical system. This helps reduce thermal damage and electrodynamic stress affecting switchgear, busbars, cables and connected equipment. Installation and replacement should be undertaken by qualified electrical personnel using suitable NH fuse-handling equipment.
Typical Applications
- Industrial switchboards and distribution panels.
- Low-voltage cable and conductor protection.
- Feeder and branch circuit protection.
- Commercial electrical distribution systems.
- Industrial machinery power supplies.
- Infrastructure and utility installations.
