Bussmann MDQ-3/4 Small Dimension Fuse, 250V

The Bussmann MDQ-3/4 is a small dimension (SML DIM) fuse rated for 250V, engineered by Bussmann to deliver dependable overcurrent protection in a compact form factor. As part of the Bussmann MDQ series of small dimension fuses, the MDQ-3/4 is sized for a 3/4A rating, making it well suited to low-current circuits where a properly matched fuse is essential for correct fault response. This fuse is commonly specified as a maintenance or replacement component in electrical and electronic equipment that uses standard small dimension fuse holders, giving technicians and facilities teams a reliable, code-appropriate way to restore circuit protection after a fuse has opened or during scheduled equipment servicing.

Key Features

  • Amperage Rating: 3/4A rating provides overcurrent protection tailored specifically to low-current circuits.
  • Voltage Rating: Rated 250V for use across a range of general-purpose electrical and electronic equipment.
  • Compact Small Dimension Design: SML DIM (small dimension) construction fits standard small-dimension fuse holders and space-constrained equipment layouts.
  • MDQ Series: Part of the established Bussmann MDQ series of small dimension fuses used widely for equipment protection and replacement.
  • Reliable Overcurrent Protection: Designed to interrupt fault current and help protect connected components and wiring from damage.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electronic Equipment Protection
  • Control Circuit Fusing
  • Instrumentation and Low-Current Circuits
  • Replacement Fuse for Small Dimension Fuse Holders
  • General Maintenance and Equipment Repair

Why Bussmann?

Bussmann is a widely recognized name in circuit protection, and the MDQ series small dimension fuse reflects that standard with its 250V rating and compact, purpose-built construction. Specifying a Bussmann MDQ-3/4 fuse helps ensure consistent, correctly matched overcurrent protection for electrical and electronic systems that rely on small dimension fuse holders, whether for new builds, maintenance, or emergency replacement work.

Bussmann MDQ-3/4 – Frequently Asked Questions

1) What amp and voltage rating does the Bussmann MDQ-3/4 fuse carry?
The MDQ-3/4 is a 3/4 amp fuse rated 250V. The 3/4A element is intended for low-current circuits, so it has to be matched to the circuit it protects - dropping it into a holder that needs a higher amperage will open on normal load, and using it where a lower rating is specified leaves the circuit under-protected. The 250V rating covers general-purpose electrical and electronic equipment at or below that voltage.
2) Will the MDQ-3/4 fit a standard small dimension fuse holder?
Yes. The MDQ series is small dimension (SML DIM) construction, built to fit standard small-dimension fuse holders and tight equipment layouts. If your holder was originally populated with an MDQ fuse, the MDQ-3/4 drops into the same clips; what you still need to confirm is that the circuit calls for 3/4A and no more than 250V.
3) What part number do I order to replace a blown MDQ 3/4 amp fuse?
Order Bussmann MDQ-3/4. That is the manufacturer part number for the 3/4 amp, 250V fuse in the MDQ small dimension series, and it is the only model on the MDQ-3/4 item. Match the printed marking on the end cap of the fuse you pulled out before ordering a quantity for stock.
4) Can I use a 250V fuse like the MDQ-3/4 on a 120V control circuit?
Yes. A fuse voltage rating is a maximum, so a 250V-rated fuse is acceptable on a lower-voltage circuit such as 120V control wiring. What cannot be substituted is the current rating: the MDQ-3/4 is a 3/4 amp device and must match what the equipment calls for.
5) Where is a 3/4A 250V small dimension fuse like the Bussmann MDQ-3/4 typically used?
Typical uses are electronic equipment protection, control circuit fusing, instrumentation and other low-current circuits, and straight replacement duty in equipment that already uses small dimension fuse holders. For an MRO or facilities crew, it is the fuse you keep on the shelf for scheduled servicing and emergency restoration of protection after one opens.
