转动操作手柄:适用于塑壳断路器,在断路器的盖上装转动操作手柄的机构,手柄的转轴装在它的机构配合孔内,转轴的另一头穿过抽屉柜的门孔,旋转手柄的把手装在成套装置的门上面所露出的转轴头,把手的圆形或方形座用螺钉固定的门上,这样的安装能使操作者在门外通过手柄的把手顺时针或逆时针转动,来确保断路器的合闸或分闸。同时转动手柄能保证断路器处于合闸时,柜门不能开启;只有转动手柄处于分闸或再扣,开关板的门才能打开。在紧急情况下,断路器处于"合闸"而需要打开门板时,可按动转动手柄座边上的红色释放按钮。
S型:四段保护带信号发送
工作状态时,不容许其他人分闸而引起停电事故,或断路器负载侧电路需要维修或不允许通电时,以防被人误将断路器合闸。
