Fuse link Etipo NH1 004139117 gF 100A 500V — cartridge fuse, fast-acting

Cartridge fuse link Etipo NH1 004139117 gF 100A 500V is a fast-acting NH1 fuse designed to protect electrical circuits and equipment in industrial and commercial installations. The fuse has a gF characteristic that provides combined protection against overloads and short circuits, ensuring rapid interruption of fault currents. It is sized for use where compact NH1 cartridges and quick response are required and fits standard NH1 fuse holders and compatible switchgear.

Advantages

The fast-acting gF characteristic delivers reliable protection for power circuits and downstream equipment by interrupting fault currents quickly while allowing normal inrush currents from motors and transformers to pass. The NH1 cartridge format offers compact installation in panels and switchgear, simplifying replacement and maintenance. Constructed to meet common industrial requirements for voltage and current ratings, the fuse provides consistent performance at 500 V and a rated current of 100 A.

Suitable for

• Protection of distribution lines and feeders in industrial and commercial electrical panels
• Short-circuit and overload protection for motors, transformers, and cable runs
• Use in NH1 fuse holders and compatible low-voltage switchgear
• Circuits requiring fast interruption with gF (general fuse) characteristics

Key specifications

• Fuse type: NH1 cartridge, fast-acting
• Rated current: 100 A
• Rated voltage: 500 V
• Characteristic: gF (general purpose, short-circuit and overload protection)
• Construction: compact cartridge suitable for standard NH1 holders

How to use

Install the cartridge fuse into a compatible NH1 fuse holder or switchgear according to the equipment manufacturer’s instructions. Ensure power is de-energized and that the fuse rating matches the circuit’s voltage and current requirements. After fitting, verify correct seating and restore power. In case of a blown fuse, replace it with an identical NH1 cartridge with the same rated current and gF characteristic to maintain appropriate protection levels.

Usage recommendations

For safe and reliable operation, use this fuse only in equipment and holders designed for NH1 cartridges and observe the rated voltage and current limits. Verify coordination with upstream and downstream protective devices to ensure selective operation where required, and follow local electrical codes and maintenance schedules when performing inspections or replacements.
