The fuse is used as a weak link within installations for equipment protection in type 2 coordinated applications. Moreover, the fuse has a body diameter of 21 mm and a length of 54 mm. This offset bolted tag fuse is a cylindrical fuse fitted with offset brackets. In addition, the fuse is widely suitable for general purpose applications in switchgear and industrial settings. 

Why Buy Eaton Bussmann Series BAO40 Slotted Tag Fuse?

A Bussmann series BA040 slotted fuse allows for an offset tag or centered configuration and differs by integrating a metal slotted tag extending off the fuse ends. It is worth noting that it protects equipment from damage caused by short circuits or overcurrent. 

What is the service life of the Eaton Bussmann Series BAO40 Slotted Tag Fuse?

A bespoke fuse can typically last for nearly ten years if there are no aging or blowing issues. 

How Do I Determine Whether My Eaton-Bussmann Slotted Tag Fuse Is Blown?

The visible gap in the wire or metallic/dark smear within the glass indicates a blown fuse and requires replacement.

    It's a fuse, and it's hard to get too excited about a fuse. Unless you need and don't have one. This is exactly what I ordered and it does exactly what I expected it to do. OK - it's a fuse, but when you need it, nothing else will work.
