What is the Residual Current Circuit Breaker (RCCB)

The use of electricity has brought a lot of convenience to modern people’s lives and work. However, electricity can easily leak, causing short circuits, burnouts, etc., leading to fires, electric shocks, and great harm to people. economic losses and life threats. Thus, Residual Current Circuit Breaker (RCCB) was born.
How Residual Current Circuit Breaker works:
The Residual Current Circuit Breaker is an electrical device that protects against leakage. When the current in the power supply exceeds the maximum current value set in advance, the Residual Current Circuit Breaker will automatically disconnect to protect the power supply from causing damage. to cause unnecessary safety incidents. In the Residual Current Circuit Breaker wiring diagram, there are neutral wires and live wires. When there is no leakage, the live wires and neutral wires are in opposite directions and the currents are equal. When there is leakage, magnetic force will be generated and the currents will be unequal. This will Disconnect the Residual Current Circuit Breaker for protection.
The function of Residual Current Circuit Breaker:
The main function of the Residual Current Circuit Breaker is that when a person has a leakage or electric shock accident, the Residual Current Circuit Breaker device will immediately cut off the power supply to ensure people’s safety and prevent electric shock accidents.
