150A 12-48V DC automatic reset circuit breaker with manual reset button for automotive, RV, marine, and boat applications.

Features: High-current thermal circuit breaker with manual reset, suitable for DC auxiliary electrical systems. When the current reaches a preset value, the resettable fuse trips automatically to protect the circuit. Circuit Protection Function: When the current reaches a preset value, the resettable fuse trips automatically to protect the circuit. It prevents overcurrents and protects electrical devices. It provides protection against overcurrents, overvoltages, ground fault currents, and overloads. Easy Installation: The built-in fuse requires no replacement. It can also be used as a battery-powered on/off switch. This circuit breaker is easy to install and can be mounted on any flat panel, wall, or in a vehicle. Materials and Wiring: The housing and components are made of highly flame-retardant and vibration-resistant plastic, ensuring a long service life. It accepts 0/2/4/8 specification power cords with adapters for direct connection to 12, 24, and 48-volt systems. Application: Provides overload and short-circuit protection when using high-current electrical equipment, such as automobiles, ships, trucks, buses, motorhomes, caravans, tractors, loudspeakers, horns, automotive battery disconnect switches, and winches.
