How does the leakage circuit breaker working?
1: the lower port of the leakage circuit breaker should be correctly connected to the live line and the neutral line.
For example, the most common 2P leakage circuit breaker has two terminals at the lower port, so when we connect, we connect the live wire and the neutral wire to the two terminals respectively, here is a live wire and a Neutral, and then make sure that the live line and the zero line form a complete loop.
Then the load can work in this loop.
2: when the leakage circuit breaker is working, if it detects leakage in the circuit or the load electrical equipment, then there will be a signal feedback value fed back to the detection coil inside the leakage protection switch. After the detection coil detects this leakage current, if it is found that the leakage current is greater than or equal to the current required by the action, that is, the conventional 30 mA, then it is determined as leakage.
3: when the actuator inside the leakage circuit breaker receives an action signal given by the detection coil in the leakage circuit breaker, the leakage circuit breaker will trip at this time.
Thus, the entire circuit is cut off, avoiding the hazard of electric shock caused by the leakage current coming into contact with the human body.
