Using fuse carriers is integral in electrical circuits, as they hold and protect fuses well, allowing safe operation and easy replacement. They also provide a point of reliable connection the fuse to the circuit and can help to prevent accidental contact with live parts. They help by isolating parts of the circuit in the event of overloads or short circuits, which may result in fires or damage to equipment. Their design may include insulating materials and markings to help those who are inspecting them or maintaining them. Bigger picture, in both industrial and residential scenarios, fuse carriers can assist with overall protection of the circuit and increase reliability and safety of electrical systems.
