塑料外壳式漏电断路器和塑料外壳式漏电小型断路器。它们之间的作用和用途有什么不同？
容量较大的漏电断路器主要用于供电回路及较大容量的负荷中，一旦发生漏电或单相短路，就会跳开断路器，起到保护的作用；
容量较小的；漏电断路器主要用于照明和民用电系统，一旦民用电器有漏电现象就跳开断路器，保护人身安全。
漏电断路器（residual current circuit-breaker），是电路中漏电电流超过预定值时能自动动作的开关。用于防止人身触电，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。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。
Plastic case leakage circuit breaker and plastic case leakage miniature circuit breaker. What are the different roles and uses between them
Large capacity leakage circuit breaker is mainly used in power supply circuit and large capacity load. Once leakage or single-phase short circuit occurs, it will jump off the circuit breaker and play a protective role.
Small capacity; leakage circuit breaker is mainly used for lighting and civil power systems, once there is leakage phenomenon in civil appliances, it will jump off the circuit breaker to protect personal safety.
The residual current circuit-breaker is a switch that can automatically operate when the leakage current exceeds the predetermined value in the circuit. Used to prevent personal electric shock, common leakage circuit breakers are divided into voltage type and current type, and current type is divided into electromagnetic type and electronic type. It should be selected according to the different requirements of direct contact and indirect contact protection.
