Plastic shell excitation auxiliary manufacturer: the role of leakage protector

Plastic shell excitation auxiliary manufacturers believe that the full name of leakage protector is residual current action protector, which is mainly composed of three parts: detection element, intermediate amplification link and operation actuator.
