The development of the industrial industry has placed increasing demands on circuit breakers. Machinery and equipment in the factory need to operate uninterrupted. Circuit breakers can quickly detect abnormalities in the circuit and immediately cut off the power supply to avoid damage to machines and equipment due to overload, short circuit or other faults, and ensure normal production operations.

In the transportation industry, circuit breakers are mainly used to protect urban rail transit and highway cables. Circuit breakers can isolate circuits and ensure safety, prevent cable overloads, short circuits and other faults from causing traffic paralysis, and ensure continuity and stability of traffic.

Circuit breakers play an important role in the construction industry. They are installed at power entrances and appliances in individual rooms to isolate the entire circuit and protect appliances from electrical faults. The construction industry requires circuit breakers to be stable and reliable and need to cope with different places and environments.

The main role of circuit breakers in the energy industry is to ensure the safety and stability of the power system. In power stations, transmission substations and power grids, circuit breakers are used to isolate faulty circuits and control the start and stop of electrical equipment to ensure the smooth operation of the power supply system.

 1. Overload protection: When the current in the circuit exceeds the rated current capacity of the circuit breaker, the circuit breaker will automatically trip and cut off the circuit to prevent wires and equipment from overheating, thus avoiding the occurrence of fire. 2. Short circuit protection: When a short circuit occurs in the circuit, that is, the current suddenly increases to a very high level, the circuit breaker will trip quickly and cut off the circuit to prevent damage to wires and equipment and avoid the occurrence of fire. 3. Personal safety protection: Circuit breakers can also protect the personal safety of residents. When a circuit failure occurs, the circuit breaker's rapid tripping can prevent electric shock accidents and protect residents from electric shock injuries. In short, the role of circuit breakers in residential communities is to ensure the safe operation of electrical systems, prevent fires and protect the personal safety of residents. Therefore, it is very important to properly install and regularly inspect and maintain circuit breakers.

Equipment in telecom base stations, communication equipment and data centers require surge protection to prevent damage due to lightning strikes or other causes in the power system
