Circuit breakers are an important type of electrical protection equipment that prevents the over-current and over-voltage overload of electrical circuits. They are divided into different types according to the characteristics of switching processes and different application fields. Among them, R21-1-7.00A-B01CH-V type circuit breaker is widely used in power distribution systems and it can provide reliable protection for electrical equipments when there is an over-current or fault.The R21-1-7.00A-B01CH-V type circuit breaker is a kind of line-operated over current protection device which combines an electromagnetic trip mechanism and an auxiliary contact switch. Its main feature is the higher contact force, which ensures a better contact effect in the system of medium and low voltage. The trip coils of R21-1-7.00A-B01CH-V circuit breaker are activated by a large current passing through the breaker. When the current exceeds the set limit, the trip coil energizes and causes the breaker to trip and open the circuit.The working principle of R21-1-7.00A-B01CH-V circuit breaker is mainly based on the principle of electromagnetic induction. When a fault current runs through a circuit, an electromagnetic field is produced which can act on the metal components of the breaker and cause an electromotive force to act on the breaker coil. When the electromotive force reaches a certain value, the breaker will be activated and trip the circuit.R21-1-7.00A-B01CH-V circuit breaker can be used in power distribution systems such as power plants, power distribution rooms, high-rise buildings and large shopping malls. In addition, it is also used in small-scale systems such as residential buildings and small residential areas. It can effectively protect the load from over-current and over-voltage overvoltage. At the same time, this type of circuit breaker can be used to protect electric motors, transformers, and other electric equipment in the system, providing reliable protection for users.In order to ensure the safe and stable operation of the load, it is necessary to set the tripping current of R21-1-7.00A-B01CH-V circuit breaker. The current setting of the breaker must be determined according to the characteristics of the load, such as the maximum current value of the load and the characteristics of electrical equipment. In addition, when selecting a circuit breaker, the technical parameters and standards of the breaker must also be taken into consideration.In addition, it is also necessary to check and maintain the R21-1-7.00A-B01CH-V circuit breaker regularly. Before the circuit breaker is put into use, a professional personnel should examine it in order to ensure the normal operation of the breaker. In addition, regular maintenance and testing should be carried out to avoid the occurrence of faults.The R21-1-7.00A-B01CH-V type circuit breaker is a widely used electrical protection device in power distribution systems which can protect the load from over-current and over-voltage overvoltage. Its working principle is mainly based on the principle of electromagnetic induction and its tripping current can be set according to the characteristics of the load. Moreover, regular inspection and maintenance should also be done to make sure it can work normally and provide reliable protection for users.
