The circuit breaker is a switch that opens the battery circuit if the current in the electrical system goes higher than the rating of the circuit breaker. A heat-activated metal disc with a contact point completes the electric circuit through the circuit breaker. If the current in the electrical system gets too high the metal disc will get hot. This heat causes a distortion of metal disc. The disc opens the contacts. The disc breaks the circuit.
Find and correct the problem that causes the circuit breaker to open. This will help prevent damage to the circuit components from too much current.
