Bussmann GMF-5 Eaton Series Time-Delay In-Line Fuse, 300V
The Bussmann GMF-5 is a time-delay in-line fuse offered through the Eaton Bussmann series, built to deliver dependable overcurrent protection in circuits rated up to 300V. Its small-dimension, in-line body is designed to install directly within a wiring run, making it a practical fit for electronic assemblies, control circuits, and other low-voltage equipment that calls for compact, code-conscious circuit protection. As a time-delay fuse, the GMF-5 is engineered to ride through brief, harmless current surges—such as motor start-up or equipment inrush current—while still opening promptly when a sustained overcurrent or short-circuit condition occurs, helping protect downstream wiring and components from damage.
Key Features
- Time-Delay Element: The GMF-5 features a time-delay design that tolerates momentary current spikes without nuisance opening, while still reacting quickly to sustained overcurrent conditions to protect the circuit.
- In-Line Configuration: Built for in-line installation, the GMF-5 mounts directly within a wiring run for straightforward integration into electronic and electrical assemblies.
- Voltage Rating: Rated for use in circuits up to 300V, the GMF-5 is suited to a range of low-voltage electronic and control-circuit applications.
- Small-Dimension Body: A compact, small-dimension fuse body allows the GMF-5 to fit space-constrained equipment enclosures and panel layouts.
- Eaton Bussmann Series: As part of the Eaton Bussmann series, the GMF-5 is backed by a widely recognized source of circuit protection components for professional electrical and electronic work.
- Reliable Overcurrent Protection: The GMF-5 helps safeguard connected wiring and components by interrupting the circuit when current exceeds safe operating levels.

Bussmann GMF-5 – Frequently Asked Questions
1) Will a Bussmann GMF fuse fit a standard 1/4 x 1-1/4 inch fuse clip or holder?
No. The GMF series body measures 2.25 inches long and .72 inches in diameter, so it will not seat in clips or holders built for the common 1/4 x 1-1/4 inch glass cartridge. Order a holder sized to the GMF body, or pick a 3AG size fuse if the holder is already in place.
2) What amp ratings does the Bussmann GMF in-line fuse come in?
Two ratings are offered: the GMF-4 and the GMF-5. Both share the same 300V rating and the same in-line body, so the only decision is the amperage your circuit calls for.
3) Can I use a 300V GMF fuse on a 120V or 240V control circuit?
Yes. A fuse may be applied at or below its voltage rating, and the GMF is rated 300V, so 120V and 240V control circuits are both within range. What you cannot do is put it on a circuit above 300V.
4) What is the interrupting rating on the Bussmann GMF fuse?
10 kiloamps. That is the fault current the fuse can safely clear, and it is the number to check against the available fault current at your panel or equipment feed before you spec it in.
5) Will a time-delay GMF fuse nuisance blow on motor or equipment inrush?
The GMF uses a time-delay element, so it rides through the brief surge of motor start-up or equipment inrush and still opens on a sustained overcurrent or short. For a circuit with no inrush, a fast-acting fuse is the better match.
6) Is the GMF fuse meant for panel mounting or in-line in a wiring run?
It is an in-line configuration, installed directly within a wiring run, and it is catalogued for panel installation in low-voltage electronic assemblies and control circuits. In practice that means a fuse holder spliced into the conductor or mounted in the enclosure, not a bolt-down block.
7) Can I stock one GMF fuse across several pieces of equipment in a building?
Within limits, yes. Both GMF ratings share one body size, one 300V rating and one 10 kA interrupting rating, so a single holder type covers both and your crib only carries two part numbers. The amperage still has to match each circuit, so do not substitute one rating for the other.
