What this product is

The Bussmann MDL-1-R is a 1 A, 250 V AC time-delay glass fuse supplied in a pack of five. The cylindrical body measures 1-1/4 in long by 1/4 in diameter and carries a 10 kA interrupt rating at 125 V AC and 35 A at 250 V AC. It is designed for circuits that experience brief inrush currents without nuisance opening.

What to check before ordering

Verify that your equipment specifies a 1 A, 250 V AC time-delay fuse with a 1-1/4 in by 1/4 in cylindrical glass body. Confirm the holder accepts a non-rejection type fuse and that the required interrupt rating meets or exceeds 10 kA at 125 V AC or 35 A at 250 V AC. Cross-reference the MDL series against any listed equivalents such as 313, 315, GDL, GDV, MDQ, MDV or MDX.

Who this suits

This pack suits technicians and hobbyists replacing blown fuses in appliances, control panels or low-voltage lighting that call for the exact MDL-1-R rating. Buyers who need a different amperage, voltage, fast-acting characteristic or a rejection-style fuse should look at other listings. Those requiring a ceramic body or higher interrupt capacity will not be served by this glass time-delay version.

Questions about this item

Does the five-pack contain anything besides the five glass fuses?

The pack supplies five 1 A 250 V AC time-delay glass fuses; no holders, tools or extra hardware are included.

How do I decide between the MDL-1-R and the other series listed such as MDQ or Littelfuse 313?

All listed series — MDL, MDQ, MDV, MDX, 313, 315, GDL, GDV — share the same 1 A, 250 V AC, time-delay, cylindrical glass construction, so choose by availability or brand preference.

What protection does the 10 kA at 125 V AC interrupt rating give in a real circuit?

It means the fuse can safely break a fault current up to 10 000 amps at 125 V AC without rupturing, protecting downstream components during a severe short.
