Bussmann GMF-1-1/4 300V Small Dimension Fuse

The Bussmann GMF-1-1/4 is a 300V small dimension fuse designed to deliver dependable overcurrent protection for compact electrical and electronic circuit applications. Carrying a 300V voltage rating, this small dimension fuse is built to help safeguard sensitive equipment, control circuits, and wiring from damaging overcurrent conditions. The GMF-1-1/4 model designation identifies this specific fuse within the broader Bussmann small dimension fuse lineup, giving electricians, panel builders, and equipment manufacturers a consistent reference point when sourcing an exact replacement or original-equipment protection device. As part of a well-known circuit protection brand, the Bussmann GMF-1-1/4 is intended for use wherever a compact, 300V-rated small dimension fuse is specifically called for by equipment design or replacement requirements.

Key Features

  • Small Dimension Design: Classified as a small dimension fuse, offering a compact form factor suited for space-constrained panels, equipment enclosures, and control circuits where standard-size fuses will not fit.
  • 300V Voltage Rating: Rated for 300V, making this fuse suitable for low-voltage overcurrent protection applications that call for this specific voltage class.
  • GMF-1-1/4 Model Designation: Clearly identified as GMF-1-1/4 within the Bussmann fuse family, simplifying accurate cross-reference, specification matching, and replacement sourcing.
  • Bussmann Manufactured: Produced by Bussmann, a recognized manufacturer of circuit protection components used across electrical and electronic systems.
  • Consistent Part Identification: The GMF-1-1/4 designation allows this exact fuse to be specified and re-ordered with confidence for maintenance, repair, and original-equipment use.

Bussmann GMF-1-1/4 – Frequently Asked Questions

1) What voltage is the Bussmann GMF-1-1/4 fuse rated for?
The GMF-1-1/4 is a 300V rated fuse. That rating is the maximum circuit voltage it is built to interrupt, so it suits low-voltage control, instrumentation, and electronic circuits. Never substitute a lower-voltage fuse into a 300V circuit; a higher voltage rating than the circuit requires is acceptable, a lower one is not.
2) What does the 1-1/4 in the Bussmann GMF-1-1/4 part number mean?
In Bussmann's GMF nomenclature the number after the series is the ampere rating, so GMF-1-1/4 is the 1-1/4 amp version of the GMF small dimension fuse. Order by the full designation, GMF-1-1/4, since the series letters alone cover a range of amperages and the amp rating has to match what the equipment or panel schedule calls out.
3) I am replacing a blown fuse in a control panel. How do I know the GMF-1-1/4 is the right one?
Read the old fuse body or the panel's fuse schedule. The replacement has to match on three points: the series (GMF), the ampere rating (1-1/4 amp), and the voltage class (300V). If the original was marked GMF-1-1/4, this is the direct like-for-like replacement and keeps the protection characteristics the equipment was designed around. If the original carries a different series letter, the body size or the speed characteristic may differ even at the same amperage.
4) Will a small dimension fuse like the GMF-1-1/4 fit a standard fuse block or holder?
Small dimension fuses are a compact format, physically smaller than standard midget or ferrule fuses, so they need a holder or clip built for that size. The GMF-1-1/4 is catalogued as a small dimension fuse, which is why it shows up in tight control panels and equipment enclosures where a full-size fuse will not fit. Match the fuse to the clip dimensions in the equipment rather than assuming a general-purpose block will hold it.
5) Can I use a Bussmann GMF-1-1/4 as a branch circuit or panel main fuse?
No. The GMF-1-1/4 is a supplementary type device for electronic equipment, control circuits, and instrumentation, not a branch circuit protective device. For feeder or branch protection you need a listed branch circuit fuse class (Class CC, J, RK5 and so on) sized to the conductor and load. Use the GMF where the equipment design or the original fuse specifically calls for a 300V small dimension fuse.
6) Is the Bussmann GMF-1-1/4 suitable for OEM equipment builds as well as repairs?
Yes, it serves both. Panel builders and equipment manufacturers spec the GMF-1-1/4 as original-equipment protection on low-voltage control and instrumentation circuits, and maintenance techs order the same designation as the exact replacement. Using the identical part number in both cases keeps the overcurrent characteristics consistent across a fleet of machines or panels.
