The working principle of the leakage protection circuit breaker in the split meter ready board

The leakage protection circuit breaker is a protection device installed in the split meter ready board. Its working principle is based on monitoring the leakage current in the circuit. When the leakage current in the circuit exceeds the set threshold, the leakage protection circuit breaker will quickly cut off the circuit to protect personal safety and electrical equipment.

Its working principle is achieved by detecting the current difference between the phase line and the neutral line in the circuit. Normally, the current should be equal between the phase and neutral wires. However, if leakage occurs, part of the current will flow to the ground or other unintended paths through the leakage path, resulting in a current imbalance between the phase line and the neutral line.

The leakage protection circuit breaker monitors the current in the circuit. Once it detects that the current difference exceeds the set threshold, it will immediately cut off the circuit to prevent the current from passing through the human body or other unsafe paths and causing the risk of electric shock. This kind of protection device is crucial for domestic and commercial electricity use. It can effectively reduce the occurrence of electric shock accidents and ensure the safety of people's lives and property.
