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

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.
