//RCD residual circuit device

RCD residual circuit device: circuit leakage current exceeds a predetermined value can automatically switch operation. Common residual current circuit breaker and current-voltage-divided into two categories, and the current model is divided into two types of electromagnetic and electronic. Leakage circuit breaker is used to prevent physical shock, depending on the different requirements of the two direct contact and indirect contact to choose shock protection.
