The residual current device is used to protect people, not systems. The moment the person goes to touch it, it creates a circuit with the ground. The current instead of staying in the household circuit, uses the human body to go to ground.
The residual current device is a device in your electrical system. It is capable of opening the circuit, that is, shutting off the power supply, the moment the current accidentally dissipates.
A residual current device offers protection in case of current leakage but not in case of overvoltage. Instead, the circuit breaker is required for this type of problem.
The AC-type residual current device works only with alternating current. Almost all systems for civil use fall into this type.
