Leakage protector and open selection

Leakage protector and open selection

Answer:

and to release the power off the release device according to its breaking reaction time can be divided into high sensitivity

Also known as leakage relay. Generally used for non-power important places
The third is not overloaded. Short-circuit protection function. Not directly split circuit, only leakage alarm RCD
