Mersen NH 2 Fuse Link 500A 500VAC gG T228522

The Mersen NH 2 fuse link is a high-performance electrical protection component engineered for industrial power distribution systems. Designed to handle a rated current of 500A at 500VAC, this gG class fuse provides comprehensive protection against both short-circuits and overloads. Its robust construction ensures reliable performance and long-term durability, making it a critical element for maintaining the safety and integrity of electrical infrastructure in demanding industrial environments.

Advantages

This fuse link offers exceptional reliability due to its high-quality manufacturing standards, ensuring consistent operation under various load conditions. The gG class designation indicates its suitability for general-purpose protection, providing a wide range of coverage for cables and equipment. Its compact NH 2 size allows for efficient integration into standard fuse bases, while the durable materials used in its construction minimize the risk of failure, thereby reducing maintenance requirements and enhancing overall system safety.

Suitable for

• Industrial power distribution boards
• Protection of electrical cables and conductors
• General industrial electrical installations
• Switchgear and control panels

This fuse may not be suitable for applications requiring specialized protection characteristics, such as semiconductor protection, which typically requires aR class fuses. It is also not intended for use in circuits exceeding its rated voltage of 500VAC or current capacity of 500A.

Key specifications

• Rated current: 500A
• Rated voltage: 500VAC
• Fuse size: NH 2
• Utilization category: gG

To use the Mersen NH 2 fuse link, ensure that the power supply is completely disconnected before installation. Insert the fuse into a compatible NH 2 size fuse base or disconnect switch, ensuring that the contact surfaces are clean and secure. Once properly seated, the circuit can be re-energized. Always use an appropriate fuse extraction handle when installing or removing the fuse to ensure operator safety.

What to consider before purchase

• Verify that the current and voltage ratings match your specific circuit requirements.
• Ensure compatibility with your existing NH 2 fuse base or holder.
• Confirm that the gG utilization category is appropriate for the intended application.

Always replace a blown fuse with one of the exact same rating and type to maintain the safety and performance of your electrical system. Regular inspections of the fuse base and connections are recommended to prevent overheating and ensure optimal contact.
