Fuse Insert NH2 gG 80 A 500 V, Eti-Polam 004185239

NH2 gG 80 A 500 V fuse insert from Eti-Polam is a replaceable NH-type (knife) fuse element intended for general-purpose low-voltage overcurrent and short-circuit protection. The insert is designed for installation in standard NH fuse holders and distribution panels where a gG characteristic is required to protect cables and downstream equipment against both overloads and fault currents up to its interrupting capacity. The product suits industrial and commercial electrical switchgear and distribution systems that require robust, standardized fuse protection.

Advantages

The NH2 gG fuse insert offers standardized dimensions for compatibility with common NH fuse bases and holders, ensuring straightforward replacement and maintenance. With an 80 A rating at 500 V, it provides stable performance for protecting conductors and equipment under typical low-voltage conditions. The gG characteristic ensures full-range protection against overloads and short circuits, making it suitable for general-purpose protection needs without complex coordination requirements.

Suitable for

• Protection of distribution circuits in commercial and industrial switchgear
• Cable and line protection in low-voltage installations
• Use in NH fuse holders and panels with gG fuse requirements
• Replacement of NH-type fuse elements in service and maintenance tasks

Key specifications

• Rated current: 80 A
• Rated voltage: 500 V AC
• Fuse type: NH2 (knife-type) insert
• Tripping characteristic: gG (general-purpose full-range)
• Application: low-voltage overcurrent and short-circuit protection

How to use

Before replacing or installing the NH2 gG fuse insert, isolate the relevant circuit and verify zero voltage with appropriate test equipment. Insert the fuse into a compatible NH fuse holder or panel slot following the manufacturer's mounting direction and ensure secure mechanical engagement of the knife contacts. After installation, restore supply and check correct operation of the protected circuit. Use only fuse bases and holders rated for NH2 inserts and matching electrical ratings to maintain safe operation.

Usage recommendations

Choose this 80 A gG NH2 insert when standardized, general-purpose protection is required for cables and equipment in low-voltage distribution. Verify coordination with upstream and downstream protective devices, and replace blown fuses with identical type and rating to preserve system protection characteristics.
