Mersen NH 2C Fuse Link 200A 500VAC gG

The Mersen NH 2C fuse link is a high-performance industrial electrical protection component engineered for reliability in low-voltage distribution systems. With a rated current of 200A and a voltage rating of 500VAC, this fuse link is designed to handle demanding electrical environments while ensuring the safety of connected equipment. Its gG characteristic indicates that it provides full-range protection, effectively interrupting both overloads and short circuits to prevent damage to electrical infrastructure.

Advantages

This NH-type fuse link offers exceptional durability and consistent performance under varying load conditions. The robust construction ensures high breaking capacity, which is essential for maintaining circuit integrity in industrial settings. By utilizing advanced materials and precise manufacturing standards, Mersen provides a reliable solution that minimizes downtime and enhances the overall safety of electrical installations.

Suitable for

• Low-voltage electrical distribution networks
• Industrial machinery and control panels
• Protection of power cables and electrical equipment
• Commercial building electrical systems

This fuse link may not be suitable for high-voltage applications exceeding 500VAC or for specialized circuits requiring different operating characteristics, such as aR (semiconductor protection) or gM (motor protection). It is intended specifically for standard industrial low-voltage protection and should not be used in environments where the fault current exceeds the rated breaking capacity of the device.

Key specifications

• Rated current: 200A
• Rated voltage: 500VAC
• Fuse size: NH 2C
• Operating class: gG
• Application: Low-voltage industrial protection

To install the Mersen NH 2C fuse link, ensure that the power supply is completely disconnected from the circuit. Insert the fuse into a compatible NH fuse base or disconnect switch using an insulated fuse handle to ensure operator safety. Verify that the fuse is firmly seated in the contacts before restoring power to the system. Always ensure that the fuse rating matches the requirements of the specific circuit being protected.

What to consider before purchase

• Verify that the 200A rating matches your circuit requirements
• Ensure compatibility with NH 2C size fuse bases
• Confirm that the 500VAC rating is sufficient for your system voltage
• Check local electrical regulations for installation compliance

For optimal performance and safety, it is recommended to replace all fuses in a three-phase system simultaneously if one has tripped. Regular inspection of the fuse base contacts for signs of oxidation or heat damage is advised to ensure long-term reliability.
