General-purpose circuit protection in commercial installations
When it may not be suitable
This fuse is not intended for use in circuits exceeding its rated voltage of 690V AC or current capacity of 20A. It should not be used in applications requiring specialized fast-acting characteristics or in environments where specific regulatory standards mandate different fuse types.
Key specifications
Dimensions: 14x51mm
Rated current: 20A
Rated voltage: 690V AC
Fuse class: gG
How to use
The fuse should be installed into a compatible 14x51mm cylindrical fuse holder or disconnect switch. Ensure that the power supply is completely disconnected before attempting to insert or replace the fuse. Align the fuse within the holder clips, ensuring a secure and firm connection to prevent overheating due to contact resistance. Once installed, the circuit may be re-energized.
What to consider before purchase
Verify that the fuse dimensions match your existing fuse holder
Ensure the 20A rating is appropriate for your circuit load
Confirm that the system voltage does not exceed 690V AC
Check if your application requires a fuse with an integrated status indicator
