Active/passive fuse module

An active/passive fuse module comprising:

• a fuse comprising:
• 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;
• a pyrotechnic interrupter (PI) coupled to the fuse body, the PI comprising:
• 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;
• and
• a crush rib disposed below the fusible element and aligned with the cutter, wherein the crush rib at least partially fills a space directly underneath the cutter and the fusible element to block the arc-quenching material from packing into the space, and wherein the crush rib provides a medium having a lower mechanical resistance than the arc-quenching material through which the cutter can pass when the PI is detonated.
