Current: 30A; Voltage: 12V-48V DC; Size: 98 x 42 x 35mm; Temperature: -10 to 50 (-14F to 122F); Wire Gauge: 8-12AWG (with inner core), 4-10AWG (without inner core) Material: Made of alloy, high-tech waterproof shell, good electrical conductivity, strong temperature and pressure resistance, apply to all 12V-48V systems Easy to use: Use it instead of the inline fuse holder. No need to remove the power cord, manual reset, just press the button and the circuit will close/open Function: The circuit breaker can protect the amplifier from damage caused by overload current or voltage. At the same time, it can also protect the power supply to prevent the battery from bursting and exploding due to short circuit Applications: Generally used in solar systems, battery charging, inverters, car audio video systems, boats, boats, bicycle use, RV and DC audio amplifier systems Note: The data are all measured manually, please allow 1-3cm error Due to differences in light and display, there may be some color differences, please refer to the actual item received.
