Reliable Full-Range Electrical Protection
The Mersen NH3GG50V100 provides full-range protection against both overload currents and high short-circuit currents. Its gG operating characteristic makes it suitable for protecting cables, conductors, switchgear and general-purpose electrical equipment throughout the complete operating range.
During an electrical fault, the fuse-link limits the peak current and energy passed into the protected circuit. This helps reduce thermal and mechanical stress on downstream components while supporting safer and more reliable operation of industrial power distribution systems.
Typical Applications
- Industrial electrical distribution panels.
- Low voltage switchboards and switchgear.
- Cable and conductor protection.
- Industrial machinery and control panels.
- Manufacturing and processing facilities.
- Commercial and industrial power distribution systems.
