Bussmann GMT-1/4A Indicating Fuse, 1/4 Amp Rated

The Bussmann GMT-1/4A Indicating Fuse is a 1/4 Amp rated fuse from the Bussmann GMT series, designed to deliver dependable overcurrent protection in low-current electrical and electronic circuits. As an indicating-style fuse, the GMT-1/4A includes a built-in visual blown-fuse indicator, allowing maintenance and service technicians to quickly pinpoint a faulted fuse without having to test each unit individually with a multimeter. This visual indication feature can meaningfully reduce troubleshooting time when diagnosing circuit faults in panels, control systems, and instrumentation equipment. Manufactured under the trusted Bussmann name in circuit protection, the GMT-1/4A is intended as a precise 1/4A replacement fuse for GMT-series applications. Technicians and electricians rely on this visual cue to speed up maintenance workflows and minimize equipment downtime.

Key Features

  • Amperage Rating: Rated at 1/4A, making it suited for low-current circuit protection applications where precise fault clearing is required.

Bussmann GMT-18/100A – Frequently Asked Questions

1) What amp ratings does the Bussmann GMT indicating fuse come in?
Two low-current ratings are offered in the GMT indicating fuse: 1/4 amp (GMT-1/4A) and 18/100 amp, which is 0.18 amp (GMT-18/100A). Both are the indicating style, so order by the exact amp value stamped on the fuse you are replacing. A GMT fuse is not interchangeable across ratings, and 18/100A is the lower of the two.
2) My equipment calls for a GMT indicating fuse. Is this the right replacement?
If the equipment or panel legend specifies a GMT-series indicating fuse, yes, provided the amp rating matches. The Bussmann GMT is sold here in GMT-1/4A and GMT-18/100A, both indicating types, intended as direct amp-for-amp replacements in GMT-series applications. Match the number on the old fuse exactly rather than rounding up.
3) How do I tell which GMT fuse has blown without pulling every one out of the panel?
That is the whole point of the indicating design. GMT fuses carry a built-in visual blown-fuse indicator, so a faulted fuse shows itself on sight and you do not have to ring out each one with a meter. In a panel full of control and signal circuits that cuts troubleshooting time considerably.
4) What kind of circuits is a GMT fuse meant to protect?
Low-current work: control circuits, panel-mount indicator and signal circuits, and electronic or instrumentation circuits. At 1/4A and 18/100A these are not branch-circuit or motor protection fuses, they protect sensitive control and signal wiring and are commonly specified as replacements in OEM and aftermarket equipment.
5) Can I substitute a standard non-indicating fuse for a GMT indicating fuse?
Not without losing function. The indicating feature is part of how the fuse is built, and GMT fuses are typically used in holders and alarm arrangements that rely on that visual indication. A plain fuse of the same amperage may clear the overcurrent but leaves your technicians testing fuse by fuse. If the panel was built around GMT indicating fuses, stay with GMT.
