The recommended choice for use with motors is the time-delay or anti-surge fuse. This type of fuse is specifically designed to handle the initial surge of current that occurs when a motor starts. Motors typically require a higher inrush current at startup compared to their running current, which can be several times greater. Time-delay fuses are built to tolerate these temporary spikes in current without blowing, allowing the motor to start successfully.

These fuses have a mechanism that delays their activation for a brief period, which prevents them from blowing due to the initial surge while still providing protection against sustained overloads or short circuits that could cause damage. As a result, using a time-delay fuse helps ensure that motors can operate effectively without unnecessary interruptions or complications.
