Bussmann MDL-1/4-R 0.25 A 250 V AC Time-Delay Glass Fuse
Time-delay glass fuse rated 0.25 A at 250 V AC with a 35 A interrupt rating
- Time-delay action protects against nuisance blows
- 25 A rating suits low-current circuits
- 250 V AC rating handles mains voltage
- 10 kA interrupt rating at 125 V AC
- 35 A interrupt rating at 250 V AC
Bussmann MDL 0.25 A time-delay fuse
This Bussmann MDL series fuse is a cylindrical glass component rated for 0.25 A at 250 V AC. It provides time-delay characteristics to tolerate brief inrush currents without opening. The part is sold as a pack of five new units for maintenance or replacement purposes.
Suits low-current AC circuits needing surge
It fits equipment that specifies a 0.25 A time-delay fuse in the 1-1/4 in by 1/4 in form factor. Buyers who need a fast-acting fuse or a higher current rating should select a different part. Circuits requiring a rejection-style base will not accept this non-rejection design.
0.25 A at 250 V AC rating
The decisive specification is the 0.25 A, 250 V AC rating combined with a time-delay curve. Interrupt ratings are 10kA at 125 V AC and 35 A at 250 V AC. Verify that the protected circuit matches these values before installation.

Questions about this item
How can I verify the fuse is working correctly after installing it in a 250 V AC circuit?
The fuse should allow normal current flow up to .25 A; if it opens, the internal element will be visibly broken through the glass body, confirming it operated as intended.
What comes in the package and are any additional components required for installation?
The pack contains five MDL-1/4-R glass fuses rated .25 A at 250 V AC; no extra parts are needed if your holder accepts 1-1/4 in by 1/4 in cylindrical fuses.
Which equivalent series should I choose if the MDL version is unavailable?
Direct equivalents include Bussmann MDQ, MDV, MDX, Littelfuse 313 and 315, and Mersen GDL and GDV series, all sharing the same .25 A, 250 V AC time-delay rating.
