The more heat used, the faster the fuse element melts the less heat applied, the longer it takes to melt the fuse element,
It's worth noting that if the fuse is going to be utilized in a situation with potentially very high or low ambient temperatures, the nominal fuse current will have to be much greater or lower.įuses are heat-sensitive devices, which means that heat (from an overcurrent) is required to melt the fuse element within the fuse. If the normal steady-state current is 10 amps, for example, a 15A fuse should be chosen (10 amps x 135% = 13.5 amps, and the next higher standard size is 15A).
Once the current value has been determined, a fuse rating of 135% of the current value should be chosen (taken to the next standard value). To choose the appropriate fuse amp erage, you must first determine the circuit's full-load steady-state current at a temperature of 25° C (68° F). 2.2 Frequently Asked Questions about 1 Amp Fuseģ.2 Frequently Asked Questions about 3 Amp FuseĤ.2 Frequently Asked Questions about 5 Amp Fuseĥ.2 Frequently Asked Questions about 10 Amp FuseĦ.2 Frequently Asked Questions about 15 Amp Fuseħ.2 Frequently Asked Questions about 20 Amp FuseĨ.2 Frequently Asked Questions about 30 Amp Fuseĩ.2 Frequently Asked Questions about 40 Amp Fuse
