Fuse Block

An automotive fuse block is a component designed to protect a vehicle's electrical system from damage caused by overloading or short-circuits. It is typically located in the engine compartment or under the dashboard and consists of a plastic or metal box containing multiple electrical fuses. The fuse block functions by interrupting the flow of electrical current when a circuit becomes overloaded or short-circuits, preventing damage to the electrical system or even a fire hazard. When a circuit is overloaded or a short circuit occurs, the electrical current flowing through the circuit increases, causing the metal wire inside the fuse to melt and break the circuit. This action protects the electrical system and prevents further damage to the vehicle. The fuse block is an essential component of a vehicle's electrical system, as it ensures the safe and reliable operation of the vehicle's electrical components. In the event of a blown fuse, the fuse block can be easily accessed and the blown fuse can be replaced with a new one of the same rating.

When selecting a fuse block, first determine how many circuits you need it to be able to service. Then confirm that amperage the fuse block needs to be able to handle. From the remaining compatible options, select the fuse block that best fits your application as well as your budget.
