Product information

Description

The Eaton NH3 Fuse Link 400A gL/gG 500V is a high-performance industrial electrical component engineered to provide robust protection for power distribution systems. Designed for demanding environments, this NH3 size fuse link ensures reliable operation by safeguarding electrical circuits against overloads and short-circuit faults. Its construction meets rigorous industrial standards, making it an essential element for maintaining safety and operational continuity in switchgear and electrical panels.

Advantages

This fuse link offers exceptional reliability and durability in high-current applications. The gL/gG characteristic provides a versatile protection profile, covering both cable and line protection effectively. Its robust design minimizes the risk of nuisance tripping while ensuring rapid disconnection during critical fault conditions, thereby protecting expensive downstream equipment and infrastructure from damage.

Suitable for

  • Industrial power distribution systems
  • Electrical switchgear and control panels
  • Protection of electrical cables and lines
  • Heavy-duty industrial machinery installations

This fuse is not suitable for low-voltage residential applications or circuits where the current rating significantly deviates from the 400A specification. It is specifically designed for industrial-grade NH3 fuse bases and should not be used in incompatible fuse holders or non-industrial environments.

Key specifications

  • Rated current: 400A
  • Rated voltage: 500V
  • Fuse size: NH3
  • Characteristic: gL/gG

To install the fuse, ensure the power supply is completely isolated and locked out. Insert the fuse link into a compatible NH3 fuse base using an appropriate insulated fuse handle. Verify that the fuse is seated firmly and that all electrical connections are tightened to the manufacturer's specified torque settings before restoring power.

What to consider before purchase

  • Verify that the fuse base size is compatible with NH3 standards
  • Ensure the system voltage does not exceed 500V
  • Confirm that the 400A rating matches your circuit protection requirements
  • Check local electrical regulations for installation compliance
Usage recommendations: Always replace fuses with an identical model to maintain the integrity of the protection system. Periodically inspect the fuse base for signs of heat damage or oxidation to ensure optimal electrical contact.
