Eaton NH2 Fuse Link 200A aM 690V

The Eaton NH2 Fuse Link 200A aM 690V is a professional-grade electrical component engineered for high-performance protection in industrial environments. Designed to meet the rigorous demands of modern electrical distribution systems, this NH2 size fuse link offers exceptional reliability and durability. It is specifically calibrated to handle the unique current profiles of motor circuits and transformers, ensuring that your equipment remains protected against electrical faults while maintaining operational efficiency.

Advantages

This fuse link stands out due to its specialized aM characteristic, which allows it to withstand high inrush currents typical of motor starting while providing precise protection against short-circuit events. Its robust construction ensures long-term stability under varying thermal conditions, minimizing the risk of nuisance tripping. By integrating this component into your electrical infrastructure, you benefit from enhanced safety standards and reduced downtime, as the fuse is built to perform consistently in demanding industrial settings.

Suitable for

• Motor circuit protection
• Transformer primary and secondary protection
• Industrial electrical distribution boards
• Heavy-duty machinery power supply systems

When it may not be suitable

This fuse is not intended for general-purpose domestic electrical applications or low-voltage circuits where a gG characteristic is required for full-range protection. It is specifically designed for motor-rated applications and may not provide the necessary protection for sensitive electronic equipment that requires fast-acting fuses.

Key specifications

• Rated current: 200A
• Voltage rating: 690V AC
• Fuse size: NH2
• Characteristic: aM (motor rated)

How to use

The fuse link should be installed by a qualified electrician into a compatible NH2 fuse base or switch-disconnector. Ensure that the power supply is completely isolated before attempting installation. Align the fuse blades with the contacts of the fuse base and press firmly until it is securely seated. Verify that the fuse is correctly oriented and that all connections are tightened to the manufacturer's specified torque settings to prevent overheating.

What to consider before purchase

• Verify that the fuse base is compatible with NH2 size links.
• Ensure the 200A rating matches the requirements of your specific motor or transformer load.
• Confirm that the system voltage does not exceed 690V.
• Check local electrical regulations regarding the use of aM characteristic fuses in your specific installation.

Usage recommendations

Always replace a blown fuse with one of the exact same rating and characteristic to maintain the integrity of your electrical protection system. Regularly inspect the fuse base for signs of oxidation or heat damage to ensure optimal contact performance.
