Material: The current circuit breaker is made of plastic and metal, which has good conductivity and strong resistance to temperature and pressure. Circuit breakers can be panel or firewall mounted for long life. Safety Feature: Unique reset button also acts as a kill switch. When the current is overloaded, the circuit breaker will automatically trip to avoid excessive current and protect the equipment. Easy to use: The circuit breaker allows you to easily connect or disconnect the circuit when needed. And, you don't need to spend more money to replace the fuse. Wide range of applications: Built-in circuit breakers are typically used in solar systems, battery loads, inverters, car audio visual systems, ships, boats, bicycle use, power systems. Both RV and DC audio amplifiers are suitable for connecting audio power lines. Attributes: Avoid excessive current and protect electrical equipment. During the self-test, if the current is overloaded, the circuit breaker will trip automatically. With a circuit breaker, you can easily connect or disconnect circuits as needed. Plus, you no longer need to spend money on replacing fuses. Suitable for car audio visual system overload protection. Also suitable for boats, bicycles, buses, motorhomes and boats.
