Eaton Bussmann MDQ Glass Fuse 2.5 A
This Eaton Bussmann MDQ series glass fuse provides time-delay circuit protection rated at 2.5 A and 250 V AC. The cylindrical body measures 1-1/4 inches long by 1/4 inch diameter and carries a 100 A interrupt rating at 250 V AC. Supplied in a pack of five for convenient replacement stock.
Suits low-voltage equipment needing time-delay
Ideal for control circuits, instrumentation and small appliances that experience brief inrush currents. Not suitable for high-current mains distribution or applications requiring a rejection-type fuse body. Buyers needing a different current rating or a ceramic body should select an alternative series.
Fits standard 1-1/4 in x 1/4 in fuse holders
The non-rejection cylindrical design drops into common panel-mount clips, PCB blocks or in-line holders without modification. Time-delay characteristic prevents nuisance opening during motor start-up or transformer energisation. Equivalent to Bussmann MDL, MDV, MDX and Littelfuse 313, 315 series for cross-reference convenience.

Questions about this item
What fuse holder size is required for the 1-1/4 in length and 1/4 in diameter glass body?
A standard 1-1/4 inch by 1/4 inch cylindrical fuse holder or clip set is needed to secure the glass body and make contact with the end caps.
Can these time-delay fuses replace fast-acting MDL series fuses in the same equipment?
Yes, the MDQ series is listed as equivalent to the MDL series, but the time-delay characteristic allows brief surges without opening, so verify the circuit needs that behavior.
How do I confirm the fuse has operated correctly after a fault event?
Inspect the glass tube; a visible break in the internal element or discoloration indicates the fuse interrupted the 100 A fault current at 250 V AC as rated.
