Reliable Protection for High-Voltage Distribution Circuits
The Mersen NH0GG69V100 protects cables and connected equipment by interrupting sustained overload currents and high-level short circuits. Its current-limiting design reduces the electrical energy passed through the system during a fault, helping minimise thermal and electrodynamic stress on conductors, switchgear and associated equipment.
The gG characteristic allows the fuse-link to provide complete general-purpose protection without requiring a separate short-circuit fuse. Its 690 V AC and 400 V DC ratings make it suitable for demanding industrial distribution systems where dependable circuit isolation and fault clearance are essential.
Typical Applications
- Industrial power distribution boards.
- Low voltage switchgear assemblies.
- Cable and conductor protection.
- Incoming and outgoing feeder circuits.
- Motor control centres.
- Industrial machinery and production equipment.
- OEM electrical panels and equipment.
