The differences and relation between the residual current monitor, residual current operated circuitbreaker and residual current operated protective relay were introduced.
介绍了剩余电流监视器与剩余电流断路器、剩余电流继电器的区别和联系。

Because bi metal element in miniature circuitbreaker is easily affected by ambient temperature change, the protective characteristic of overload will be changed with ambient temperature change.
由于小型断路器的双金属元件易受环境温度变化的影响，其脱扣特性也将随之改变。

The circuitbreaker after getting command from the protective relay, disconnects only the faulted element.
