DC12V Circuit Breaker, Circuit Protection Switch for Car, Boat, Bicycle, Stereo Audio (100A)

When the power is off, there's no need to spend time and effort disassembling and installing the fuse core without opening or closing anything; it's a single click. Made of alloy with good conductivity, it stabilizes the current, protects the battery, and prevents leakage. Press the red elliptical button; the long handle springs back, and the circuit breaker is switched off. After resetting the long red handle, the circuit breaker is switched back on. Automatic trip protection: when the fuse is subjected to a high current, it will trip and reset automatically. The fuse is used to protect the amplifier and the power supply.
