【Material】: The circuit breaker is made from a high-conductivity alloy material. Protects electrical devices from excessive current. 【Function】: Fuse holders prevent overcurrent and overload protection for amplifiers, audio electronics, audio/video systems, and accessories in cars, boats, marine vehicles, and mopeds, protecting their amplifiers from power surges. 【Easy Installation】: Surface mountable, can be mounted on a control panel or firewall, includes a protective bolt insulator. The inline fuse does not need to be replaced. 【Wide Application】: Commonly used in auxiliary and accessory circuits for trucks, buses, recreational vehicles, and marine applications. Also used in battery charging and audio systems. Description: - When the system is overvolted or short-circuited, the circuit breaker trips and protects your equipment. - Surface-mount switchable circuit breakers are commonly found in auxiliary and accessory circuits in trucks, buses, RVs, and marine systems.
