Bussmann GLR-5 Eaton Bussmann Series Fast-Acting Fuse, 300V

The Bussmann GLR-5 is a fast-acting fuse from the Eaton Bussmann series, purpose-built as a small-dimension fuse rated for 300V circuits. Engineered to respond quickly to overcurrent and short-circuit conditions, this compact fuse is designed to protect sensitive equipment, wiring, and control circuitry in applications where a small physical footprint and dependable fast-acting performance are required. As part of the widely recognized Eaton Bussmann series lineup, the GLR-5 model delivers the consistent, code-compliant quality that electrical professionals expect when specifying an exact-replacement fuse for panels, control circuits, instrumentation, and OEM equipment that call for this specific catalog number.

Key Features

  • Voltage Rating: Rated for 300V, making it suitable for circuits and equipment designed around this maximum voltage threshold.
  • Fast-Acting Response: Provides a quick-opening response to overcurrent and short-circuit events, helping to limit potential damage to downstream conductors and connected components.
  • Small-Dimension Design: Compact, small-dimension fuse body sized to fit fuse holders, blocks, and equipment enclosures that call for this space-saving form factor.
  • Eaton Bussmann Series: Produced under the Eaton Bussmann series, one of the most widely specified circuit-protection product lines in commercial and industrial electrical work.
  • Model GLR-5: Carries the exact GLR-5 catalog designation, simplifying cross-reference and helping ensure the correct fuse is selected for exact replacement in existing installations.
  • Circuit Protection Function: Functions as a sacrificial overcurrent protection device, interrupting current flow before excessive heat or current can damage protected equipment.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Overcurrent Protection in 300V-Rated Circuits
  • Control Panels and Panelboards
  • Industrial and Commercial Equipment Protection
  • OEM Equipment Requiring Exact GLR-5 Fuse Replacement
  • Small-Dimension Fuse Holders and Fuse Blocks
  • Instrumentation and Control Circuit Protection

Why Bussmann?

Bussmann fuses, manufactured under the Eaton Bussmann series, are specified across commercial, industrial, and OEM electrical systems where dependable, fast-acting circuit protection is required. The GLR-5 small-dimension, 300V-rated design reflects the engineering consistency that electrical professionals and maintenance teams rely on when an exact-match replacement fuse is needed to keep equipment running safely and circuits protected against overcurrent conditions. Choosing the correctly specified Bussmann GLR-5 helps maintain the intended level of overcurrent protection designed into the original equipment or panel.

Bussmann GLR-1-1/2 – Frequently Asked Questions

1) What amp ratings does the Bussmann GLR fuse come in?
Two GLR ampere ratings are offered: GLR-1-1/2 (1.5 amp) and GLR-5 (5 amp). Both carry the same 300V rating and the same small-dimension body, so the only thing you are choosing is the ampere rating. Order by the exact catalog number, since the fuse body gives no other way to tell them apart once installed.
2) Will the Bussmann GLR-5 fit my existing fuse holder?
The GLR body measures .72 inches in diameter, the standard small-dimension instrument fuse form factor. If your holder, block, or clip set is specified for GLR or GLH small-dimension fuses, it drops in. Measure the clip spacing on an existing fuse before swapping from a different family, because a ferrule diameter mismatch will not seat properly.
3) Can I use a 300V fuse like the GLR-5 in a 480V control circuit?
No. The GLR-5 is rated 300V maximum and must not be applied above that. For a 480V control circuit you need a fuse rated at or above the circuit voltage; a fuse applied over its voltage rating may not safely interrupt a fault. The GLR series is a low voltage device intended for control and instrumentation circuits at 300V or less.
4) My equipment nameplate calls out GLR-5 specifically. Can I substitute a different fuse?
When the equipment or panel schedule names GLR-5, use GLR-5. The ampere rating, the 300V rating, and the .72 inch small-dimension body all have to match for the protection designed into the original equipment to hold. Substituting a different family changes clearing speed or physical fit, and an undersized voltage rating is a safety problem rather than a convenience one.
5) Is the GLR-5 a fast-acting or time-delay fuse, and does that matter for motor loads?
Fast-acting. The GLR-5 opens quickly on overcurrent and short circuit, which is what you want ahead of instrumentation, control circuitry, and electronics. It is the wrong choice where there is an inrush surge to ride through, such as a motor or transformer primary, because a fast-acting element can clear on normal startup current. For those loads specify a time-delay fuse instead.
6) How many fuses come in a pack of the Bussmann GLR?
Each pack contains 100 fuses. That quantity suits MRO and facility stock where a single ampere rating is standardized across many panels, or an OEM building the same control assembly repeatedly. If you maintain both ratings on site, stock GLR-1-1/2 and GLR-5 separately.
7) Where in a system is the GLR-5 fuse normally installed?
It is a panel-mounted device, used in control panels and panelboards, fuse blocks and small-dimension holders, instrumentation and control circuits, and OEM equipment that calls out the GLR catalog number. It is not a branch-circuit or service-entrance fuse.
