Abstract

An automatic actuator assembly including a passive actuator assembly and a detection assembly is operatively coupled to an arc reduction assembly. The passive actuator assembly is coupled to the arc reduction assembly and structured to move the arc reduction assembly between a disengaged, first configuration and an engaged, second configuration.

First claim

What is claimed is:

1. An automatic actuator assembly for an arc reduction assembly provided in a housing assembly having a door, said arc reduction assembly having a first electrically conductive contact and a second electrically conductive contact and being configurable in a disengaged first configuration where the first electrically conductive contact is spaced from and not electrically connected to the second electrically conductive contact and an engaged second configuration where the first electrically conductive contact is in contact with and electrically connected to the second electrically conductive contact, said arc reduction assembly being coupled to an electrical component within the housing assembly, wherein said arc reduction assembly is structured to be in the disengaged first configuration during operation of the electrical component, said automatic actuator assembly comprising:
a passive actuator assembly coupled to said arc reduction assembly and structured to configure said arc reduction assembly in one of the said first configuration or said second configuration;
a detection assembly, said detection assembly structured to detect at least one of the presence of a user adjacent said housing assembly or a movement of said housing assembly door from a closed position to an open position; and
said detection assembly further structured to provide a proximity communication to said passive actuator assembly in response to detecting either the presence of the user adjacent said housing assembly or the movement of said housing assembly door from the closed position to the open position, wherein the passive actuator assembly is structured to configure said arc reduction assembly in said engaged second configuration in response to the proximity communication.

2. The automatic actuator assembly of claim 1 wherein said passive actuator assembly is structured to receive and react to the proximity communication and to move between a passive actuator first configuration and a passive actuator second configuration.

3. The automatic actuator assembly of claim 1 wherein:
said detection assembly includes a sensor assembly;
