Mersen GGC Series Fast-Acting Miniature Glass Fuse, 6.3x32mm Ferrule

The Mersen GGC Series is a fast-acting miniature glass fuse family built for supplemental overcurrent protection in electronic and industrial equipment. Each fuse in this series shares the same 6.3x32mm (1/4" x 1 1/4") glass body with ferrule terminals for clip-style mounting, and the series is offered across a Motor FLA range from 0.75A up to 30A so it can be matched to the specific load being protected. All ratings in the family are rated up to 250V AC and are RoHS compliant, making the GGC Series a dependable, code-conscious choice for panel-mount fuse holders and control circuit protection across a wide span of equipment.

Key Features

  • Fuse Size: 6.3x32mm (1/4" x 1 1/4") glass body sized for standard clip-mount fuse holders, common to every rating in the GGC Series.
  • Motor FLA Range: Available from 0.75A through 30A, allowing the correct fuse to be selected for the connected motor or control load without changing mounting hardware.
  • Fast-Acting Speed: Fast-Acting characteristic responds quickly to overcurrent conditions to help protect connected equipment across the full amperage range.
  • Ferrule Terminal Connection: Ferrule-style ends are designed for secure clip mounting and simple replacement, shared across all options in the series.
  • Voltage Rating: Rated up to 250V AC for supplemental circuit protection applications, regardless of the selected amperage.
  • Glass Body Construction: Insulating glass body allows visual inspection of the fuse element for quick troubleshooting.
  • Fuse Class: Supplemental fuse class intended for equipment-level protection rather than branch-circuit duty.
  • AC Rated: Designed for AC circuit applications per the source specification, consistent across the entire GGC Series.

Mersen GGC30 – Frequently Asked Questions

1) Is a fast-acting fuse like the GGC right for a motor circuit, or do I need time-delay?
GGC is a fast-acting characteristic, which suits electronic loads, instrumentation, and control circuits where there is little inrush. A motor with a real starting surge will usually nuisance-open a fast-acting fuse sized to FLA; for that duty a time-delay fuse such as the Littelfuse CCMR Series is the correct type. Use GGC where you want quick clearing on a resistive or electronic load.
2) Can a Mersen GGC fuse be used for branch-circuit protection instead of a Class CC fuse?
No. The Mersen GGC Series is a supplemental fuse class intended for equipment-level protection rather than branch-circuit duty. Where the drawing calls for branch-circuit or motor-circuit fusing, a Class CC fuse such as the Littelfuse CCMR040 of the CCMR Series is the correct family - that one is a Class CC time-delay fuse rated 40A, above the 30A top end of the GGC range, and its rejection-style design will not drop into a 6.3x32mm clip holder.
3) Is a Mersen GGC fuse the right replacement for a metering fuse in a power monitor?
Not usually. The Mersen GGC Series is rated 250V AC, and metering circuits are commonly fused at a higher voltage - the Square D PowerLogic energy meter fuse pack, for example, is a set of three rated 0.5A 600V. For a PowerLogic meter, order the meter fuse pack. The GGC is the choice for 250V AC control and electronic equipment circuits in the 0.75A to 30A range.
4) What voltage and AC/DC rating do Mersen GGC fuses carry?
250V, and the GGC Series is specified for AC circuits. That covers 120V and 240V control transformers, instrumentation, and machine control circuits. It is not rated for DC service, so for a DC bus or battery circuit use a fuse with a published DC rating.
5) What amp ratings does the Mersen GGC Series come in?
The GGC family spans 0.75A through 30A, so you can match the fuse to the actual motor FLA or control load while keeping the same 6.3x32mm clip mounting. Order by the amperage you need, for example GGC3/4 at 0.75A or GGC30 at 30A.
6) What else could I use to replace a 6.3x32mm glass fuse if I need another brand?
Littelfuse builds the same 1/4 x 1-1/4 glass tube format: the AGU Series glass tube fuse is a boxed-package option, and the AGA Series is available in individual ratings such as the AGA5 at 5A. Match the amperage, the 250V class rating, and the speed characteristic of the fuse you are pulling out before substituting, since the GGC is fast-acting.
7) Can I standardize all the fuse holders in my control panels on one size using GGC?
Yes, that is the practical reason to spec the series. Every rating from 0.75A to 30A shares the same 6.3x32mm ferrule body and clip mounting, so one holder type carries the whole range and your spares shelf only needs different amperages, not different holders.
8) What should I use instead of a Mersen GGC fuse if the load has an inrush surge?
The Mersen GGC Series has a fast-acting characteristic, which responds quickly to overcurrent and can open on the start-up surge of an inductive load. For those circuits a time-delay fuse is the better match - the Littelfuse CCMR040 is a Class CC time-delay fuse rated 40A. If the application is a steady electronic or control load, the fast-acting GGC at 250V AC is the intended choice.
9) How does the Mersen GGC compare to the Littelfuse BLF midget fuse?
Both are fast-acting 250V fuses, so the protection characteristic is comparable. The difference is the body: the Littelfuse BLF Series is a midget fuse with a laminated tube body, while the Mersen GGC uses a glass body that lets you see the element for troubleshooting. If you need visual inspection at the panel, the GGC is the one to carry; if you need the midget form factor the holder was built for, the BLF is the match.
10) Why a glass body fuse instead of a ceramic or laminated tube one?
The GGC body is glass, so you can see whether the element has opened without pulling the fuse, which speeds up troubleshooting on a live panel. Where you want an opaque, higher-strength tube instead, the Littelfuse BLF Series is a midget fast-acting fuse rated 250V in a laminated tube.
11) Is the Mersen GGC fuse RoHS compliant for a spec that requires it?
Yes, the GGC Series is RoHS compliant, and that applies across every amperage in the family from 0.75A to 30A. Useful on institutional and OEM specs that call out RoHS for all installed components.
