Hager LNH2TMM NH00 Non-Insulated Knife Link 400A Silver-Plated Contacts

The Hager LNH2TMM is a professional-grade non-insulated NH00 knife link engineered for robust performance in electrical distribution systems. Designed to handle a rated current of 400A, this component serves as a reliable solid link within fuse bases, effectively completing electrical circuits where overcurrent protection is not required at the specific point of installation. Its construction prioritizes durability and efficient power transmission, making it a standard choice for industrial and commercial electrical infrastructure.

Advantages

The primary advantage of this knife link is the integration of high-quality silver-plated contacts. This specialized surface treatment significantly reduces contact resistance, ensuring optimal conductivity and minimizing energy losses during operation. The non-insulated design allows for straightforward installation in compatible NH00 fuse bases, providing a secure and stable connection that maintains system integrity under continuous load conditions.

Suitable for

• Electrical distribution boards and panels
• Industrial power supply systems
• Bridging circuits where fuse protection is not necessary
• Replacement of fuse links in non-protected circuit segments

When it may not be suitable

This product is not suitable for applications requiring overcurrent or short-circuit protection, as it acts strictly as a solid conductor. It should not be used in circuits where safety regulations mandate the presence of a fuse or circuit breaker for fault protection.

Key specifications

• Size: NH00
• Rated current: 400A
• Contact material: Silver-plated
• Type: Non-insulated knife link

How to use

To install the Hager LNH2TMM, ensure the electrical circuit is fully de-energized and locked out according to safety protocols. Insert the knife link into the corresponding NH00 fuse base, ensuring it is seated firmly and aligned correctly with the contact clips. Verify that the connection is secure before restoring power to the system.

What to consider before purchase

• Verify that your existing fuse base is compatible with the NH00 size standard.
• Ensure the 400A rating is appropriate for your specific circuit load requirements.
• Confirm that the application does not require fuse-based overcurrent protection.

Usage recommendations

Always use appropriate insulated tools and personal protective equipment when handling electrical components to prevent accidental contact with live parts. Ensure that the installation is performed by a qualified professional in accordance with local electrical codes.
