- 32 V AC rating suits low-voltage automotive and generator systems
- 1 kA interrupt capacity breaks fault current safely
- Glass cylindrical body allows visual inspection of element
- Pack of five provides spares for maintenance or replacement
What this fuse is and who needs it
The Bussmann MDL-25 is a time-delay glass fuse rated at 25 A and 32 V AC with a 1 kA interrupt rating. It suits low-voltage circuits that experience brief inrush currents, such as generator control panels or accessory wiring. The cylindrical, non-rejection body fits standard 1-1/4 in by 1/4 in fuse holders. This pack contains five fuses for spares or multiple circuits.
Installation notes and common pitfalls
Insert the fuse into a compatible holder until the metal end caps seat firmly; no tools are required. The glass tube lets you verify the element visually after a fault. Do not use this fuse in circuits exceeding 32 V AC or where a higher interrupt rating is specified. A common error is substituting a fast-acting fuse, which will nuisance-blow on motor start-up.
The specification that decides fit
The critical figure is the 25 A rating combined with the 32 V AC voltage limit and 1 kA interrupt capacity. If your equipment calls for a different amperage, a higher voltage, or a rejection-style fuse, this MDL-25 will not provide correct protection. Always match all three values to the device label before installing.

Questions about this item
How can I confirm the 25 A 32 V AC glass fuse is working after installation?
With power off, measure continuity across the fuse using a multimeter; a low resistance reading shows the element is intact and the fuse is ready to protect the circuit.
What comes in the pack and what must I buy separately?
The pack contains five MDL-25 glass fuses rated 25 A at 32 V AC; a compatible fuse holder or panel is not included and must be purchased separately.
Which equivalent series should I choose if I need a direct replacement for the MDL-25?
Equivalent series listed are Bussmann MDQ, MDV, MDX, Littelfuse 313 and 315, and Mersen GDL and GDV — select the one that matches the 25 A, 32 V AC, 1 kA interrupt rating and 1-1/4 in x 1/4 in dimensions.
