When it may not be suitable
This fuse is not intended for general-purpose domestic electrical circuits or low-voltage household applications. It is specifically calibrated for semiconductor protection and may not provide the correct tripping characteristics for standard motor protection or general cable overload protection.
Key specifications
Rated current: 350A
Rated voltage: 690V
Fuse size: NH2
Characteristic: gR
How to use
The fuse link should be installed into a compatible NH2 size fuse base or disconnect switch. Ensure that the power supply is completely isolated before attempting installation or replacement. The fuse must be inserted firmly into the contacts, ensuring proper alignment to prevent overheating or poor electrical connection. Always use appropriate insulated tools and personal protective equipment when handling high-voltage components.
What to consider before purchase
Verify that the fuse base is compatible with NH2 size links
Ensure the 350A rating matches your circuit load requirements
Confirm that the gR characteristic is appropriate for your specific semiconductor protection needs
Check the voltage rating of your system to ensure it does not exceed 690V
Usage recommendations
Regularly inspect the fuse contacts for signs of oxidation or heat damage. Replace the fuse immediately if it has been triggered by a fault, as internal components may be compromised even if the exterior appears intact.
