Circuit Breakers are designed to automatically interrupt electrical circuits in the event of overcurrent or short circuit conditions. These devices help prevent damage to electrical components and mitigate the risk of electrical fires by rapidly disconnecting the circuit when abnormal conditions are detected. Circuit breakers come in various types, including thermal-magnetic and electronic, offering diverse applications in residential, commercial, and industrial electrical systems. The price of circuit breakers varies significantly based on factors such as current rating, voltage, and the specific type of circuit breaker. Industrial-grade or high-current circuit breakers, along with those with advanced features like arc fault detection or ground fault protection, may come at a higher cost. When buying circuit breakers, choose ones with the right current rating and voltage for your electrical system. Consider protection type based on application. Assess features like arc fault detection or ground fault protection. Follow local codes, consider size and mounting requirements for proper installation.
