Cartridge fuses provide overcurrent protection in agricultural, automotive, data center, industrial, power generation, and residential settings. Available with a broad range of ampere ratings, cartridge-type fuses also come in many sizes and types. The cartridge fuses for commercial and passenger vehicles, for instance, often come housed in color-coded thermoplastic cases. Solar power system cartridge fuses, however, resemble standard glass fuses. When selecting the type of cartridge fuse for your application, check the specifications for time-delayed, medium-acting, or fast-acting performance.
