A surge protective device (SPD) module includes a printed circuit board (PCB), a first electrode, a second electrode, and a varistor electrically connected between the first and second electrodes. The SPD module forms a housing assembly defining a chamber containing the varistor. The PCB forms a portion of the housing assembly.

Surge protective devices

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.

Devices for active overvoltage protection including varistors and thyristors

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.

Devices for active overvoltage protection

An overvoltage protection device includes a first electrode member, a second electrode member, and a varistor assembly. The varistor assembly includes: a plurality of varistor wafers each formed of a varistor material; and at least one electrically conductive interconnect member connecting the varistor wafers in electrical parallel between the first and second electrode members. The varistor wafers are axially stacked between the first and second electrodes.
