Key specifications

• Rated current: 40A
• Rated voltage: 500VAC
• Fuse size: NH 2C
• Characteristic: gG
• Application: Industrial circuit protection

How to use

The Mersen NH 2C fuse link should be installed by a qualified professional into a compatible NH fuse base or disconnect switch. Ensure that the power supply is completely isolated before attempting installation or replacement. Align the fuse blades with the contact clips 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 according to the manufacturer's torque specifications.

What to consider before purchase

• Verify that the fuse base size matches the NH 2C form factor.
• Ensure the 40A rating is appropriate for the specific circuit load.
• Confirm that the system voltage does not exceed 500VAC.
• Check local electrical regulations regarding the use of gG class fuses.

Usage recommendations

Always replace a blown fuse with one of the exact same rating and characteristic to ensure continued system safety and compliance with electrical standards. Do not attempt to repair or bypass a fuse link.
