Bussmann GLR-1 Series 300V Fast-Acting Fuse, Small Dimension

The Bussmann GLR-1 is a fast-acting fuse from the Eaton Bussmann series, engineered to deliver reliable overcurrent protection in a compact, small-dimension form factor. Rated for 300V, this GLR-1 fuse is built to respond quickly under fault conditions, helping shield sensitive circuits, control devices, and connected equipment from damage caused by short circuits and overload events. The small-dimension body of the GLR-1 makes it well suited for compact fuse holders, control panels, and other space-constrained electronic assemblies where a dependable, fast-responding overcurrent device is required. As part of the Bussmann series lineup from Eaton, the GLR-1 is designed to support consistent, code-conscious circuit protection for a wide range of low-voltage electrical and electronic systems.

Key Features

  • Small-Dimension Body: Compact fuse construction sized to fit standard small-dimension fuse holders and clips, supporting installation in tight panel and equipment layouts.
  • Fast-Acting Response: Fast-acting (fast-blow) fuse element opens quickly when current exceeds rated levels, helping limit fault energy and protect downstream components.
  • 300V Voltage Rating: Rated for use at up to 300V, making the GLR-1 suitable for a broad range of low-voltage control, instrumentation, and electronic circuit protection applications.
  • Bussmann Series Construction: Manufactured under the Eaton Bussmann series brand, a widely specified source for circuit protection fuses used across commercial, industrial, and OEM applications.
  • Dependable Overcurrent Protection: Designed to provide consistent, repeatable performance for protecting circuits from damaging overcurrent and short-circuit conditions.
  • Compact Form Factor: The GLR-1's small-dimension profile helps conserve space in densely populated fuse blocks and equipment enclosures.

Bussmann GLR-1 – Frequently Asked Questions

1) How many fuses come in a pack of the Bussmann GLR-1?
The GLR-1 ships 100 fuses to a pack, so it is bought as a bulk quantity rather than a single piece. That suits panel shops, OEM assembly, and MRO stockrooms that burn through small-dimension fuses and want one shelf item covering many openings. If you only need one or two replacements, you are still buying the full 100-count box.
2) Is the Bussmann GLR-1 a fast-acting or time-delay fuse?
Fast-acting. The GLR-1 element opens quickly once current goes past the rating, which is what you want ahead of sensitive control and instrumentation circuits where you are trying to limit fault energy. It is the wrong choice where a load has a large inrush at startup, such as a motor or transformer primary, because a fast-blow element will clear on the inrush. Those circuits want a time-delay (dual-element) fuse instead.
3) What voltage circuits can a Bussmann GLR-1 fuse be used on?
It carries a 300V rating, so it covers typical low-voltage control, instrumentation, and electronic circuits, including 120V and 240V control wiring. Do not apply it above 300V. A fuse used over its voltage rating may not interrupt the arc cleanly on a fault.
4) Will a GLR-1 fit a small-dimension fuse holder or fuse block?
Yes. The GLR-1 is built as a small-dimension fuse, so it is sized for the small-dimension holders, clips, and blocks used in control panels and compact equipment assemblies. It is not a ferrule or blade-style class fuse and will not drop into a holder built for those bodies.
5) What is the manufacturer part number for ordering the Bussmann GLR-1?
Order it as GLR-1, from the Bussmann GLR small-dimension series (Eaton Bussmann series). That exact designation is what distinguishes it from the other amperage ratings in the GLR family, so quote the full GLR-1 part number rather than just the series when you order or cross-reference.
6) Where is a GLR-1 fuse typically used in a building or piece of equipment?
Control panels and electronic assemblies, low-voltage instrumentation and control circuits, industrial and commercial electrical equipment, OEM gear that needs a compact fuse, and replacement duty in existing panelboards and fuse blocks. For a property manager or MRO buyer, the common case is restocking the control-circuit fuses in HVAC, pump, and lighting control panels.
7) Is there a spec sheet available for the Bussmann GLR-1 fuse?
Yes, Eaton publishes a data sheet for the GLR small-dimension fuse covering the series data. It is worth pulling before you standardize a panel on this fuse so the element characteristics match what the equipment maker specified.
