Alarm Indicating Fuses

We sell Littelfuse alarm fuses which are a very special fuse and designed for use in a specific holder. They feature a mouse-trap style element that springs open when the fuse blows to trigger a contact and signal the open circuit to a control panel. Once the fuse is blown it must be replaced.
