DZ15LE漏电断路器生产厂家 浙江乐清三福 漏电断路器（residual current circuit-breaker）电路中漏电电流超过预定值时能自动动作的开关。常用的漏电断路器分为电压型和电流型两类，而电流型又分为电磁型和电子型两种。 漏电断路器用于防止人身触电，应根据直接接触和间接接触两种触电防护的不同要求来选择。 Leakage breaker (residual current circuit-breaker) the leakage current of the circuit exceeds a predetermined value when the automatic operation of the switch. Common leakage circuit breaker is divided into two categories of voltage and current, the current type is divided into two kinds of electromagnetic and electronic. Leakage circuit breaker is used to prevent physical shock, should be selected according to the different requirements of direct contact and indirect contact with two electric shock protection to.
