1. An apparatus comprising:
a high-voltage module comprising:
a current interrupter;
an actuation system coupled to the current interrupter;
a sensor system; and
a terminal assembly comprising a terminal configured to electrically connect to an external electrical device;
a user interface; and
an electrically insulating assembly between the user interface and the high-voltage module, the electrically insulating assembly comprising: an operating housing and an electrically insulating operating rod in the operating housing,
wherein the electrically insulating operating rod extends between the user interface and the actuation system of the high-voltage module; the operating housing extends between the user interface and the terminal assembly; and wherein, in operational use, the user interface is grounded and the high-voltage module is at a system voltage.
