Maxifuses

The maxifuse is a relatively new circuit protection device that is designed to be a serviceable replacement for the fusible link cables previously used in the automotive industry. It operates very similar to the minifuse except that the operating current is much higher. Maxifuses are available in 20-60 amp ratings. Currently, Saturn vehicles use only a 30 amp maxifuse. The blow characteristics have been designed to match cable temperature curves for overload conditions.


All maxifuses are located in the underhood junction block (UHJB).
