Why Choose the Mersen NH2GG69V315 NH Fuse Link?
The Mersen NH2GG69V315 is a heavy-duty NH2 size gG fuse link designed to provide full-range protection for industrial power distribution systems, switchgear and electrical installations. Rated at 315 A and 690 V AC, this high rupturing capacity fuse protects cables and equipment against both overloads and short-circuit faults in demanding industrial environments.
Its gG operating characteristic provides complete protection across the full operating range, allowing the fuse to interrupt currents from sustained overloads through to maximum breaking capacity. This makes it suitable for protecting feeders, distribution circuits, switchboards and industrial electrical equipment.
The NH2GG69V315 features a robust ceramic body, silver-plated blade contacts, live gripping tags and an integrated double indicator for rapid identification of an operated fuse. Designed to DIN NH standards, it is intended for installation in compatible NH2 fuse bases and switch-fuse disconnectors.

Reliable Protection for Industrial Power Distribution
The Mersen NH2GG69V315 is designed to protect industrial cables, switchgear and electrical equipment by safely interrupting overloads and severe short-circuit currents before damage can occur. Its current-limiting characteristics help reduce thermal and mechanical stress on electrical installations while improving operational reliability.
The fuse should be installed in a compatible NH2 fuse base or switch disconnector and replaced only by qualified personnel using an approved NH fuse puller and suitable personal protective equipment.
Typical Applications
- Industrial power distribution systems.
- Main electrical switchboards.
- Cable and feeder protection.
- Industrial switchgear assemblies.
- Manufacturing and processing facilities.
- Commercial and industrial electrical infrastructure.
