Trip unit providing remote electrical signal to remotely indicate that an arc reduction maintenance mode is remotely enabled, and electrical switching apparatus including the same
Abstract:
An electrical switching apparatus includes separable contacts; an operating mechanism structured to open and close the separable contacts; and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes an input structured to receive a remote signal to remotely enable an arc reduction maintenance mode, a first circuit structured to enable the arc reduction maintenance mode in response to the received remote signal, and a second circuit structured to provide an electrical signal remote from the trip mechanism in order to remotely indicate that the arc reduction maintenance mode is remotely enabled.
Abstract(Chinese):

电气开关装置包括可分离触点; 构造成打开和关闭可分离触点的操作机构; 以及与所述操作机构配合的跳闸机构，以使所述可分离触点脱开。 跳闸机构包括被构造为接收远程信号以远程启用电弧消除维护模式的输入，响应于所接收的远程信号而实现电弧消除维护模式的第一电路，以及被构造成提供电信号的第二电路 远程脱扣机构，以远程指示电弧还原维护模式远程启用。
