Circuit breakers are important safety devices in electricity meters used to automatically protect circuits and prevent damage caused by overloads and short circuits.
1. Overload Protection: When the current exceeds the set value but does not reach the short-circuit current, the circuit breaker will automatically trip to protect the line from overheating and damage due to prolonged overcurrent.
2. Short-Circuit Protection: In the event of a short circuit or a rapid increase in current, the circuit breaker will quickly disconnect the circuit to prevent equipment damage and safety accidents.
3. Isolation Function: During maintenance or when needed, the circuit can be manually disconnected to create a clear disconnection point, ensuring the safety of operators.
4. Control Function: Used in electricity meter systems to control the on/off state of circuits and achieve electricity management.
