Choosing a fuse requires consideration of multiple key parameters, such as:
maximum operating current
Maximum working voltage
ambient temperature
Overload current and its corresponding melting time
Possible maximum fault current
Facing special situations such as pulse, lightning current, startup surge, and transient spikes in the line
Dimensional requirements, such as length, width, and height
Standards followed, such as UL/CSA/VDE/TUV/CCC/CQC, etc
Installation methods, such as patch, plug-in, bolt or base, etc.
