Overview

Circuit breakers are essential safety devices that protect electrical circuits from damage caused by overloads or short circuits. They automatically interrupt the flow of electricity when a fault is detected, preventing potential fires and equipment damage. Circuit breakers are used in residential, commercial, and industrial settings to ensure electrical safety and reliability.
