Key specifications
Rated current: 144A
Rated voltage: 400V
Fuse size: NH2 (WT-2)
Characteristic: gTr
Application: 100kVA transformers
How to use
The fuse link should be installed into a compatible NH2 size fuse base by a qualified electrical professional. Ensure that the power supply is disconnected before installation to prevent electrical hazards. Align the fuse blades with the contact slots of the base and press firmly until it is securely seated. Verify that the connection is tight and that the surrounding environment is free from moisture or debris that could interfere with electrical conductivity.
What to consider before purchase
Verify that your transformer rating is exactly 100kVA
Ensure the existing fuse base is compatible with the NH2/WT-2 size standard
Confirm that the system voltage does not exceed 400V
Check local electrical regulations for installation requirements
Usage recommendations: Always replace fuses with the exact same type and rating to maintain system safety. Regularly inspect the fuse base for signs of oxidation or heat damage to ensure optimal performance.
