Circuit overcurrent protection is important. Inadequate selection of fuses can lead to the breakdown of equipment, resulting in replacement costs.
The function of a fuse is to interrupt an uncontrolled fault current or overcurrent before serious damage can occur, such as the overheating of equipment.
Because a fuse is designed using a fusing element, it is particularly suited for reliable interruption of short-circuits. With overcurrents up to 2x or 3x the rated current, a fuse becomes less accurate and, as such, not so well suited for these conditions. Other overcurrent protection measures such as electronic protection, thermal overload elements or additional fuses are then necessary.
Normal Operation
After Switching ON under normal operating conditions, a fuse is subjected to a maximum operating current and a maximum operating temperature. A derating of the rated current is therefore usually necessary since a fuse is rarely operated at the set ambient temperature of 23 ˚C. As an example, let’s look at a scenario using a time-lag SMD fuse such as the UMT 250 from SCHURTER. With an operating temperature of 60 ˚C, the fuse needs to be derated by 17%, i.e., when the operating current is 1 A @ 60 ˚C, a rounded-up fuse value of 1.25A (1A / 0.83) is necessary.
Fuses can be in accordance with IEC 60127 or UL 248-14. Because of the different definitions between the two standards, fuses are not directly interchangeable as follows: fuses in accordance with IEC 60127 may be operated continually at 100% of the rated current value, whereas fuses in accordance with UL 248-14 only at 75%. UL 248-14 specifies a minimum of 4h operating time at rated current.
The self-heating effect of time-lag fuses is less than that of quick-acting. This can be seen from the typical values of voltage drop. For example, a 2 A 5x20 mm glass time-lag fuse has a typical voltage drop of 60 mV, whereas a typical quick-acting version is 90 mV. This difference is evident by the thicker fuse element (higher melting value I2t, see point 2) that is necessary for time-lag fuses. It should also be noted that fuses are heated by the current until element melts (opens) and interrupts the circuit.
