30A Car Circuit Breaker 12V-24V DC Waterproof Car Circuit Breaker with Manual Reset Power Circuit Breaker Fuse Holder for Car Stereo Audio

【High-Quality Material】Made from a high-quality alloy with good electrical conductivity and resistance to high temperatures and pressures. The fittings have a waterproof rubber sleeve, and the internal screws are made of pure copper to ensure a long service life. 【Applications】Car Audio Fuse Box, 12V-24V DC, 20A, 30A, 50A. Ideal replacement for your AGU, ANL, or AFS fuse holder. It is typically used for overload protection of DC systems such as solar panels, battery chargers, inverters, and audio-visual systems in cars, boats, trucks, electric vehicles, buses, caravans, etc. 【Surge Protection】30A, 12V 24V DC | The circuit breaker provides critical protection to your system when it is overloaded. In case of a short circuit, the circuit breaker trips immediately, the long handle automatically cuts off the power supply, thus protecting your devices. Once the fault is repaired, the fuse holder can be reused by returning the long handle to its original position. 【Usage】 Press the oval button on the fuse; the long handle will open and the current will be cut off. Circuits can then be easily connected if necessary. (Do not interrupt the power supply by directly engaging the long handle with your hand, as this will damage the circuit breaker.) Once the connection is established, return the open long handle to its original position, and the circuit breaker will re-engage. 【Function】 Compatible with audio power cables. Prevents overcurrents and protects electrical devices. Compatible with all current ratings from 20A to 150A, 12V/24V system voltages.
