Fuse carriers with fuse fail neons

Sailbadthesinner
I have encountered a distribution board that uses RT18-32X 10x38 fuse carriers that have a built in neon connected across the fuse to indicate fuse failure.

Cute feature but my immediate thought was that these do not provide isolation of the outgoing way.  Are they suitable for use in a DB ?

    I've taken a closer look at these fuse carriers.

    The fuse, as you would expect, disconnects from the supply and load terminals as you open the hinged cover.

    The neon has contacts to the fuse in the cover that don't make to the supply and load terminals.

    So if you leave the fuse out you've got an air gap and good isolation.
