Abstract Residual current operated circuit-breaker with integral overcurrent protection is an importance protection device to prevent electric shocks and electric fire. False wiring in the installation can make it difficult to operate or cause indescribable trip. The present paper makes analysis of false wiring of residual current operated circuit-breaker with interal overcurrent protection based on its operation principle in combination with related code.

Key words　Residual current operated circuit -breaker with integral overcurrent protection Residual current device False wiring

 

摘　要　带过流保护的剩余电流动作断路器是防止触电事故和电气火灾的重要保护装置， 安装时的误接线会使之难于投运或发生莫名其妙的跳闸。 试从原理入手并结合相关规范，对带过流保护的剩余电流动作断路器误接线进行分析。
