Introduction to Residual Current Circuit Breaker with Overcurrent Protection
A Residual Current Circuit Breaker with Overcurrent Protection (RCCB with overcurrent protection) is a crucial electrical safety device. It combines the functions of a residual current circuit breaker, which can detect leakage currents and quickly cut off the power supply to prevent electric shock and fire hazards caused by leakage, and an overcurrent protection function that can protect the electrical circuit from damage due to excessive current, such as short – circuits or overloads. This integrated device is widely used in residential, commercial, and industrial electrical systems to ensure the safety and reliability of electricity use.
