300A 12-48 Volt DC self-resetting circuit breaker with manual reset button for applications in motor vehicles, caravans, ships and boats (300 Ampere)

Features: High-current thermal circuit breaker with manual reset switch, suitable for DC auxiliary electrical systems. Once the current reaches a preset value, the resettable fuse automatically interrupts the circuit for protection. Protection function: Once the current reaches a preset value, the resettable fuse automatically interrupts the circuit for protection. Prevents overcurrent and protects electrical equipment. Protection against overcurrent, overvoltage, residual current, and overload. Easy installation: The built-in fuse does not need to be replaced. The switch can also be used as a battery-operated on/off switch. The circuit breaker is easy to install and can be mounted on any flat surface, wall, or in a vehicle. Material and wiring: The housing and components are made of highly flame-retardant and vibration-resistant plastic, ensuring a long service life. It is compatible with 0/2/4/8 mm² power cords and includes adapters for direct connection to all 12-, 24-, and 48-volt systems. Applications: It provides overload and short-circuit protection for high-current electrical devices such as those found in cars, boats, trucks, buses, motorhomes, caravans, tractors, loudspeakers, horns, vehicle battery disconnect switches, and winches. This audio circuit breaker is a thermal high-current circuit breaker with a manual reset switch, suitable for DC auxiliary electrical systems.
