Bussmann DMM-B-11A fuse used in many popular late-model DMMs for the 10A current range. The arc-quenching sand filler and glass fiber-reinforced melamine tube gives it a high rupture capacity (HRC). It is rated at 1000V (AC or DC) and is capable of interrupting 20,000 amps.
I find it interesting that the zig-zag shaped element has separated into several pieces, no doubt by design. Fortunately it did its job and the multimeter and forgetful multimeter user it protected suffered no damage.

How about silica jell verus “sand” ?
How about “gel” versus “jell”. 🙂
