Hager LNH3355MK NH3 355A 500V gG Fuse Link

The Hager LNH3355MK is a high-performance NH3 size fuse link engineered for robust industrial electrical protection. Designed to operate at a rated current of 355A and a voltage of 500V, this component features a gG characteristic, making it suitable for general-purpose protection against both short-circuits and overloads. It serves as a critical safety element in electrical distribution systems, ensuring operational stability and circuit security in demanding professional environments.

Advantages

This fuse link offers exceptional reliability and consistent performance under varying electrical loads. Its construction adheres to strict industrial standards, providing effective protection for power management infrastructure. The gG characteristic ensures a comprehensive range of protection, covering everything from low-level overloads to high-current short-circuit events, thereby safeguarding expensive equipment and preventing downtime in critical electrical installations.

Suitable for

• Industrial electrical distribution boards
• Power supply systems in manufacturing facilities
• Protection of electrical circuits in commercial buildings
• General-purpose electrical infrastructure requiring high-capacity protection

This fuse link may not be suitable for applications requiring specialized characteristics such as aR (semiconductor protection) or gM (motor protection). It is also not intended for use in low-voltage residential circuits where smaller fuse sizes are standard.

Key specifications

• Fuse size: NH3
• Rated current: 355A
• Rated voltage: 500V
• Characteristic: gG
• Width: 66 mm
• Height: 150 mm

How to use

The Hager LNH3355MK should be installed into a compatible NH3 fuse base or disconnect switch. Ensure that the power supply is completely isolated before attempting installation or replacement. The fuse should be inserted firmly into the contacts of the fuse base, ensuring proper alignment. Always use appropriate insulated tools and personal protective equipment when handling electrical components to prevent accidental contact with live parts.

What to consider before purchase

• Verify that the fuse base is compatible with the NH3 size standard
• Ensure the circuit voltage does not exceed the 500V rating
• Confirm that the 355A current rating matches the requirements of your electrical system
• Check that the gG characteristic is appropriate for the specific protection needs of your installation

Usage recommendations

Always replace fuses with the exact same type and rating to maintain the integrity of the electrical protection system. Periodic inspection of the fuse base contacts is recommended to ensure a secure connection and prevent overheating.
