The pure earth leakage pure residual current circuit breaker serves to protect people and not installations. The moment a person touches it, it creates a circuit with the earth. The current instead of staying in the home circuit, uses the human body to go to ground.
The residual current circuit breaker, also called circuit breaker, is a device in your electrical system. It is able to open the circuit, i.e. to interrupt the supply of energy, when the current is accidentally lost.
A pure residual current circuit breaker offers protection in case of current leakage but not in case of overvoltage. For this type of problem, a circuit breaker is required instead.
The AC residualcurrent circuit breaker operates only with alternating current. Almost all civil installations fall into this type.
