Circuit Breakers

991204 Application Field and Working Principle

Circuit breakers are electrical devices used to break the electrical circuit, when a certain level of current passes through it. They are used to safeguard electrical power equipment, such as transformers, motors, and other electrical components, from damage by excessive current flows.Circuit breakers come in different types, such as the thermal-magnetic circuit breaker, which works based on the thermal tripping device and the magnetic tripping device. In this type of circuit breaker, a bimetal coil helps control and measure the temperature of the power lines. When the temperature exceeds a certain level, it trips the magneanotripper, activating the circuit breaker to break the circuit.The electromagnetic circuit breaker is also a type of circuit breaker which works based on the interaction between a movable armature and a magnetic field. When a certain amount of current passes the circuit breaker, the moving armature induces a magnetic force, which forces the contacts in the circuit breaker to open and thus breaks the circuit. Other types of circuit breakers are the AC and the DC motor circuit breakers, which are used mainly for controlling the starting current of motors. In these circuit breakers, when a certain amount of current passes through it, it triggers the motor, and the motor creates a magnetic field, which activates the circuit breaker.The applications of circuit breakers are seen in many types of equipment, such as transportation systems, medical equipment, and residential and industrial applications. In addition, circuit breakers are also used in power plants, which help protect the system from overloading or other faults in the power line.In order to ensure proper operation, the settings of the tripping device, current, and the contacts must be calibrated properly. In addition, if a power surge or short circuit occurs, the circuit breaker must be reset manually. Overall, the advantages of circuit breakers are that they are able to protect electrical components and systems from damage, and they can be easily reset manually, if needed. In addition, they are cost-effective, since they can be set to trip at a lower current, thus saving power and money.
