1、执行保护方式可以设置为关闭、报警、跳闸三种模式，关闭模式下只测量对应项目值，不对其测试值做任何判断和产生保护动作。报警模式下当检测到该值超过动作设定值时经延时，达到动作延时时间时发出报警声音，在延时过程中，剩余电流值若下降到小于剩余电流动作值时延时清零，不会发出报警声音。
1. The execution protection mode can be set to three modes: close, alarm and trip. In the close mode, only the corresponding item value is measured, and no judgment and protection action are made for its test value. In the alarm mode, when the value is detected to exceed the action set value, the alarm sound will be sent out when the action delay time is reached after the delay. In the delay process, if the residual current value drops to less than the residual current action value, the alarm sound will not be sent out.
2、剩余电流实际有效动作值200×90%即（50mA~1000mA）×90%
2. The actual effective operating value of residual current is 200 × 90%, i.e. (50mA ~ 1000mA) × 90%
3、额定电流设置优选值：
3. Rated current setting preferred value:
壳架等级额定电流（A）  额定电流100  16, 20, 25, 32, 40, 50, 63, 80, 100
Rated current of frame class (a) rated current 100 16, 20, 25, 32, 40, 50, 63, 80, 100
