Automotive and fleet fuses provide overcurrent protection in DC-powered vehicles and equipment. These electrical-protection devices prevent damage to electric wiring and components by opening a circuit when current flow exceeds the fuse's current rating. Automotive blade fuses (the most commonly used automotive fuse) are plug-in fuses with a plastic housing and metal blade contacts. Automotive glass fuses are cylindrical fuses typically found in older, North American–built vehicles. Automotive cartridge fuses are rectangular fuses for protecting wiring harnesses. High-current automotive fuses are bolt-on devices for power-distribution components such as batteries, alternators, and heavy-gauge cables. Forklift fuses bolt into place on lift trucks, scissor lifts, pallet movers, and other heavy-duty battery-powered equipment.
