Hager LNH20144M4T NH2 Fuse Link 144A gTr 400V

The Hager LNH20144M4T NH2 fuse link is a high-performance electrical protection component engineered for demanding industrial environments. Designed specifically for transformer protection, this fuse link provides reliable circuit interruption at a rated current of 144A. It is optimized for 400V electrical distribution networks, ensuring consistent safety and operational stability for critical infrastructure.

Advantages

This fuse link offers exceptional durability and precision in electrical protection. Its gTr characteristic is specifically calibrated for the protection of distribution transformers, allowing it to handle the specific thermal and electrical stresses associated with these systems. The robust construction ensures long-term reliability, minimizing downtime and protecting expensive equipment from potential overcurrent damage within industrial power grids.

Suitable for

• Protection of distribution transformers
• Industrial electrical distribution networks
• Low-voltage power supply systems
• Electrical installations requiring gTr characteristic protection

When it may not be suitable

This product is not intended for use in domestic household circuits or applications that do not require the specific gTr characteristic for transformer protection. It is also unsuitable for systems operating at voltages significantly exceeding the 400V rating.

Key specifications

• Size: NH2
• Rated current: 144A
• Rated voltage: 400V
• Characteristic: gTr
• Width: 42 mm
• Depth: 72 mm
• Height: 150 mm

How to use

The fuse link should be installed into a compatible NH2 fuse base or switch-disconnector by a qualified electrician. Ensure that the power supply is disconnected before installation to prevent electrical hazards. Align the fuse blades with the contact clips of the base and press firmly until it is securely seated. Verify that the installation complies with local electrical safety standards and that the fuse rating matches the specific requirements of the transformer being protected.

What to consider before purchase

• Verify that the NH2 size is compatible with your existing fuse base
• Ensure the 144A rating matches the transformer capacity
• Confirm that the gTr characteristic is required for your specific application
• Check the physical dimensions to ensure fitment within your electrical cabinet

Usage recommendations: Always use appropriate personal protective equipment when handling electrical components. Regularly inspect the fuse link for signs of physical damage or discoloration, and replace it immediately if the indicator shows that the fuse has operated.
