Abstract
An active/passive fuse module including a fuse having an electrically insulating fuse body, first and second endcaps disposed on opposing ends of the fuse body, a fusible element extending through the fuse body between the first endcap and the second endcap, and an arc quenching material disposed within the fuse body and surrounding the fusible element. The fuse module further includes a pyrotechnic interrupter (PI) coupled to the fuse body, the PI having a housing defining a shaft, a piston disposed within the shaft, a drive pin extending from the piston into the fuse body, the drive pin terminating in a cutter disposed adjacent the fusible element, and a pyrotechnic ignitor disposed within the shaft above the piston configured to detonate upon receiving an initiation signal from a controller, whereby the piston and the drive pin are forcibly driven through the shaft causing the cutter to separate the fusible element.
