A safety circuit is a crucial component in electrical systems designed to protect both equipment and users from potential hazards. It ensures that if a fault occurs, such as an overload or short circuit, the circuit will automatically disconnect power, preventing damage or injury. Safety circuits are commonly used in industrial machinery and household appliances to enhance safety. These circuits often include devices like fuses, circuit breakers, and emergency stop buttons. By monitoring electrical flow, they can quickly react to unsafe conditions, ensuring that machinery stops operating when necessary. This proactive approach helps maintain a safe working environment and reduces the risk of accidents.
