Bussmann MDQ-3 Glass Fuse 3A 250V AC 5 PK

SKU CH-AE1R-776XA

A pack of five glass time-delay fuses rated 3 A at 250 V AC with a 100 A interrupt rating

  • Time-delay protection handles temporary surges without nuisance blowing
  • 100 A interrupt rating at 250 V AC clears faults safely
  • Glass cylindrical body allows visual inspection of element status
  • Standard 1-1/4 in x 1/4 in size fits common fuse holders
  • Pack of five provides ready spares for maintenance needs

3 A 250 V AC Glass Fuse Pack

This pack contains five Bussmann MDQ-3 glass fuses rated at 3 A and 250 V AC. They provide time-delay protection for circuits that experience brief inrush currents. The cylindrical glass body allows visual inspection of the element. Suitable for replacing failed fuses in compatible equipment.

Verify Fuse Rating and Interrupt Capacity

Confirm the circuit requires a 3 A time-delay fuse with a 100 A interrupt rating at 250 V AC. Check that the holder accepts a 1-1/4 in by 1/4 in cylindrical glass fuse. Ensure the application does not need a rejection-style fuse, as this series is non-rejection.

Fits Standard 1/4 Inch Fuse Holders

The fuse fits holders designed for 1-1/4 in length by 1/4 in diameter cartridges. It replaces Bussmann MDL, MDQ, MDV, MDX and equivalent Littelfuse 313, 315 or Mersen GDL, GDV series fuses. Using the correct rating restores circuit protection without modifying the holder or wiring.

Questions about this item

What comes in the 5-pack and is any extra hardware needed?

The pack contains five MDQ-3 glass fuses rated 3 A, 250 V AC with a 100 A interrupt rating. No additional hardware is required for installation.

How do I decide between the MDQ series and the listed equivalents such as 313 or GDL?

All listed series — MDQ, MDL, MDV, MDX, 313, 315, GDL, GDV — share the same 3 A, 250 V AC rating and 1-1/4 in by 1/4 in dimensions, so any will fit the same holder.

What does the 100 A interrupt rating mean when the fuse is in circuit?

It means the fuse can safely break a fault current up to 100 A at 250 V AC without rupturing, protecting downstream components during a short-circuit event.
