Eaton NH Fuse Link 500A 500V gL/gG Size 3 500NHG3B

The Eaton 500NHG3B is a professional-grade NH fuse link engineered to provide robust electrical protection in industrial power distribution systems. With a current rating of 500A and a voltage rating of 500V, this size 3 fuse link is specifically designed to safeguard electrical circuits against overloads and short circuits. Its gL/gG characteristic ensures reliable performance across a wide range of fault conditions, making it an essential component for maintaining the integrity of electrical installations and protecting sensitive equipment from damage.

Advantages

This fuse link offers exceptional reliability and durability, even in demanding industrial environments. Its design focuses on safety and consistent performance, ensuring that electrical systems remain protected during unexpected power surges or faults. The high-quality construction materials contribute to a long service life and stable operation, reducing the need for frequent maintenance and minimizing downtime in critical power distribution networks.

Suitable for

• Industrial power distribution boards
• Protection of electrical cables and equipment
• Heavy-duty electrical installations
• Switchgear and control gear assemblies

When it may not be suitable

This fuse link is not intended for use in low-voltage residential applications where smaller fuse sizes are required. It is also not suitable for circuits exceeding its 500V voltage rating or for applications requiring a different characteristic curve than the gL/gG standard.

Key specifications

• Rated current: 500A
• Rated voltage: 500V
• Fuse size: 3
• Characteristic: gL/gG
• Application: Industrial electrical protection

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. The fuse link is designed to be inserted into a compatible NH size 3 fuse base or disconnect switch. Ensure the power supply is completely isolated before attempting to install or replace the fuse. Align the fuse blades with the contacts 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 before commissioning.

What to consider before purchase

• Verify that the fuse base is compatible with size 3 NH fuse links.
• Ensure the circuit current and voltage requirements align with the 500A and 500V ratings.
• Check that the gL/gG characteristic is appropriate for the specific protection needs of the installation.

Usage recommendations: Always replace a blown fuse with one of the exact same type and rating to maintain the safety and functionality of the electrical system. Do not attempt to repair or bypass a fuse link under any circumstances.
