辅助触头:与断路器主电路分、合机构机械上连动的触头,主要用于断路器分、合状态的显示,接在断路器的控制电路中通过断路器的分合,对其相关电器实施控制或联锁。继电器等输出信号。壳架等级额定电流100A为单断点转换触头,225A及以上为桥式触头结构,约定发热电流为3A;壳架等级额定电流400A及以上可装两常开、两常闭,约定发热电流为6A。操作性能次数与断路器的操作性能总次数相同。
报警触头:用于断路器事故的报警触头,且此触头只有当断路器脱扣分断后才动作,主要用于断路器的负载出现过载短路或欠电压等故障时而自由脱扣,报警触头从原来的常开位置转换成闭合位置,接通辅助线路中的指示灯或电铃、显示或提醒断路器的故障脱扣状态。由于断路器发生因负载故障而自由脱扣的机率不太多,因而报警触头的寿命是断路器寿命的1/10。报警触头的工作电流一般不会超过1A。
分励脱扣器:分励脱扣器是一种用激励的脱扣器,它的电压与主电路电压无关。分励脱扣器是一种远距离操纵分闸的附件。当电源电压等于额定控制电源电压的70%-110%之间的任一电压时,就能可靠性的分断断路器。分励脱扣器是短时工作制,线圈通电时间一般不能超过1S,否则线就会被烧毁。塑壳断路器为防止线圈烧毁,在分励脱扣线圈串联一个微动开关,当分励脱扣器通过衔铁吸合,微动开关从常闭状态转换成常开,由于分励脱扣器电源的控制线路被切断,即使人为的按住按钮,分励线圈始终不会再通电这就避免了线圈烧损情况的产生。当断路器再扣合闸后,微动开关重新处于常闭位置。
