Selecting a suitable circuit breaker requires a comprehensive evaluation of circuit parameters, load characteristics, installation environment, and protection requirements. The core considerations are ensuring the rated voltage matches the system voltage, the rated current is greater than the load current but less than the conductor current-carrying capacity, and the breaking capacity (Icu) is higher than the expected short-circuit current.
The working principle of a circuit breaker revolves around the core logic of monitoring, judgment, and execution. Through its built-in tripping mechanism and arc-extinguishing system, it achieves normal circuit connection and disconnection control and rapid interruption of faulty circuits. Specifically, it can be divided into normal operating mode and fault protection mode. The arc-extinguishing system is a crucial auxiliary mechanism ensuring reliable tripping.
Circuit breakers are core devices in power systems, enabling circuit switching control and automatic fault protection. They are widely used in all scenarios, from household electricity to high-voltage power grids. Their core functions are overload/short circuit/leakage protection, equipment safety, power supply stability, and fire and electric shock prevention.
