ANL Fuse Holder is a high-current circuit protection device designed for automotive, marine (boat), ATV, trailer, and high-power audio/video systems. IT prevent electrical overloads, short circuits, and overheating in circuits using 1/0/2/4-gauge wires. Its primary role is to protect sensitive equipment (e.g., inverters, battery chargers) and wiring by interrupting excessive current flow, thereby preventing fire hazards and equipment damage.
