The document describes a simplified SPICE behavioral model for simulating the behavior of fuses in circuits. The model allows users to set parameters like current rating, fuse factor, internal resistance, and normal melting value to simulate how long it takes a fuse to blow under different current conditions. Simulation results are presented demonstrating how fusing time varies based on steady direct current levels and different current waveforms providing the same peak current. Instructions are provided on installing the model libraries and symbols for use in SPICE simulations.
