 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.
