Hager LNH3500M NH3 500A 500V gG Fuse Link

The Hager LNH3500M is a high-performance NH3 size fuse link engineered for robust industrial electrical protection. Designed to handle demanding electrical environments, this component provides reliable circuit interruption in the event of overloads or short circuits. Its construction ensures consistent performance and safety within electrical distribution systems, making it a dependable choice for maintaining operational integrity in professional settings.

Advantages

This fuse link offers exceptional reliability due to its gG characteristic, which provides full-range protection against both low-level overloads and high-level short-circuit currents. The NH3 size standard ensures compatibility with a wide range of industrial fuse bases, facilitating straightforward integration into existing electrical panels. Its durable design is built to withstand the thermal stresses associated with high-current applications, ensuring long-term stability and protection for sensitive downstream equipment.

Suitable for

• Industrial electrical distribution boards
• Power supply protection in manufacturing facilities
• Protection of electrical cables and equipment against short circuits
• Heavy-duty electrical installations requiring 500A capacity

When it may not be suitable

This fuse link is not intended for use in low-voltage residential circuits or applications requiring a different physical size standard than NH3. It is also unsuitable for systems exceeding the 500V voltage rating or for applications where a different tripping characteristic, such as aR or gM, is specifically required for semiconductor protection.

Key specifications

• Rated current: 500A
• Rated voltage: 500V
• Fuse size: NH3
• Characteristic: gG (general purpose)

How to use

The Hager LNH3500M should be installed by a qualified electrician into a compatible NH3 fuse base or disconnect switch. Ensure the power supply is completely isolated before attempting installation or replacement. Align the fuse link with the contact blades of the fuse base and press firmly until it is securely seated. Always verify that the current and voltage ratings match the requirements of the circuit being protected before energizing the system.

What to consider before purchase

• Verify that the fuse base is compatible with NH3 size components.
• Ensure the circuit load does not exceed the 500A nominal rating.
• Check that the system voltage does not exceed 500V.
• Confirm that the gG characteristic is appropriate for the specific protection requirements of your application.

Usage recommendations: Always replace blown fuses with identical units of the same rating and characteristic to maintain system safety. Do not attempt to repair or bypass a blown fuse link, as this poses a significant fire and safety hazard.
