  • Publication number: 20240120728
    Abstract: A circuit protection device is provided. The circuit protection device includes an active energy absorber that is coupled between two power lines in an electrical power distribution system and is configured to selectively conduct fault current responsive to overvoltage conditions. The active energy absorber includes an overvoltage protection module that includes two thyristors that are connected in anti-parallel with one another and a varistor that is connected with the overvoltage protection module as a series circuit. The series circuit including the varistor and the overvoltage protection module is connected between the power lines.

  • Publication number: 20240097430
    Abstract: An overvoltage protection device module includes an electrically conductive first electrode, an electrically conductive housing electrode, and a varistor member formed of a varistor material and electrically connected between the first electrode and the housing electrode. The housing electrode includes a housing end wall and a housing side wall collectively defining a housing cavity, and first and second housing members joined together at a joint. The first housing member forms a first portion of the housing side wall and the second housing member forms a second portion of the housing side wall. The varistor member is disposed in the housing cavity.
