Bussmann GMF-1 Series Time-Delay In-Line Fuse, 300V

The Bussmann GMF-1 is part of the Eaton Bussmann series of time-delay, small-dimension in-line fuses, engineered to deliver dependable overcurrent protection in a compact form factor. Rated 300V, the GMF-1 is built with a time-delay (slow-blow) fuse element that allows momentary inrush currents and short-duration current surges to pass without causing the fuse to open, helping to minimize nuisance interruptions in circuits where brief overcurrent conditions are a normal part of operation. As an in-line fuse, the GMF-1 is designed to install directly within the circuit conductor path, making it a practical choice for equipment and wiring configurations that call for a small, in-line overcurrent protective device. Backed by the Eaton Bussmann name, the GMF-1 is manufactured to help support consistent, repeatable performance in circuit protection applications across a range of electrical and electronic systems.

Key Features

  • Time-Delay Operation: The GMF-1 uses a time-delay (slow-blow) characteristic that allows momentary overcurrent conditions and inrush currents to pass without opening the fuse element, reducing nuisance interruptions in normal operating conditions.
  • 300V Voltage Rating: Rated for 300V, providing overcurrent protection suited to a range of low-voltage electrical and electronic circuits.
  • Small-Dimension In-Line Design: Compact in-line construction allows the GMF-1 to be installed directly in the circuit conductor path where panel or enclosure space is limited.
  • Eaton Bussmann Series: Manufactured as part of the Eaton Bussmann series fuse lineup, built to Bussmann engineering standards for consistent, repeatable overcurrent protection.
  • Reliable Circuit Protection: Designed to help safeguard connected equipment and wiring from damage caused by sustained overcurrent conditions.
  • Space-Saving Form Factor: The GMF-1's compact, small-dimension body supports installation in tight enclosures, control boxes, and equipment where board or panel space is at a premium.

Why Bussmann?

Bussmann, part of Eaton, is a recognized name in circuit protection, and the GMF-1 reflects that heritage with a time-delay, 300V-rated in-line fuse built for dependable performance. The time-delay design helps the GMF-1 ride through momentary current fluctuations that would otherwise cause a standard fuse to open unnecessarily, while its small-dimension in-line body keeps installation straightforward in space-constrained equipment. Choosing a Bussmann series fuse like the GMF-1 helps ensure consistent, code-compliant overcurrent protection for professional electrical and electronic applications where reliability matters.

Bussmann GMF-1 – Frequently Asked Questions

1) Is the Bussmann GMF-1 a slow-blow fuse or a fast-acting one?
The GMF-1 is a time-delay (slow-blow) fuse. Its element lets inrush current and short-duration surges pass without opening, so motors, transformers and other loads with a normal startup spike don't nuisance-trip it. If your circuit needs the fuse to clear instantly on any overcurrent (sensitive electronics, semiconductor protection), a time-delay fuse is the wrong choice and you want a fast-acting type instead.
2) What voltage can the Bussmann GMF-1 fuse be used on?
It carries a 300V rating, which covers typical low-voltage control circuits, instrumentation and equipment wiring. Don't apply it above 300V. Circuit voltage must be at or below the fuse rating for the fuse to interrupt safely.
3) What does "in-line" mean on the GMF-1 fuse, and does it need a panel fuse block?
In-line means the fuse installs directly in the conductor path rather than in a panel-mounted block, so it suits equipment, control boxes and harnesses where there's no room for a fuse holder in a panel. You still need a holder or clips sized for this small-dimension body to retain it in the circuit.
4) What exact part number do I order for a Bussmann GMF series 300V time-delay fuse?
Order by manufacturer part number GMF-1, from the Bussmann GMF series. The GMF designation covers the small-dimension time-delay family; the number after the dash is the amp rating, so confirm you want the 1 amp version before ordering.
5) Can I use the Bussmann GMF-1 as a replacement fuse in OEM equipment?
Yes, it's used for OEM equipment and aftermarket fuse replacement, along with control panel and control circuit protection and electronic instrumentation. Match the original fuse's amp rating, voltage rating and time-delay characteristic; swapping a fast-acting original for a time-delay fuse changes how quickly the circuit clears.
