Mersen GGC Series Fast-Acting Glass Tube Fuse, 1/4" x 1-1/4"
The Mersen GGC Series is a fast-acting glass-body fuse family sized 1/4" x 1-1/4" (6x32mm), engineered for clip-mount installation with ferrule connection terminals. This listing is available in amperage options ranging from 0.1A to 1.5A, with both ratings covered under the 250VAC voltage rating that applies across the GGC Series' lower-amperage lineup. The GGC Series is UL Listed and CSA Certified for dependable overcurrent protection in control, instrumentation, and general electronic circuits. The clear glass body lets technicians visually confirm fuse condition without pulling the fuse for testing, speeding up troubleshooting during panel and equipment servicing. Whether specifying the 0.1A option for sensitive low-current circuits or the 1.5A option for slightly higher-draw electronic loads, engineers can standardize on the same glass-body, ferrule-terminal, clip-mount platform for consistent installation and stocking.
Key Features
- Fast-Acting Response: Opens quickly on overcurrent conditions to protect sensitive downstream circuits and components.
- Glass Body Construction: Clear glass housing, 1/4" x 1-1/4" (6x32mm), allows quick visual inspection of the fuse element and blown-fuse condition.
- Clip Mounting: Designed for standard clip-style fuse holders and fuse blocks common in control panels.
- Ferrule Terminals: Ferrule-style connection ends provide secure, low-resistance contact in the fuse clip.
- Amperage Options: Available in this listing as 0.1A or 1.5A to match specific circuit protection requirements.
- Voltage Rating: 250VAC rating applies to both the 0.1A and 1.5A options in this listing.
- Compact Diameter: Product diameter of 0.25 in for standard 1/4" x 1-1/4" fuse clips and holders.

Mersen GGC1-1/2 – Frequently Asked Questions
1) Will the Mersen GGC fuse fit a standard 1/4 x 1-1/4 inch fuse clip or holder?
Yes. The GGC glass tube fuse is a 1/4" x 1-1/4" (6x32mm) body with a 0.25 in diameter and ferrule ends, so it drops into standard clip-style fuse holders and fuse blocks. It is a clip-mount fuse, not a screw- or panel-terminal type, so you need clips or a block that grips the ferrules.
2) What amp ratings does the Mersen GGC glass fuse come in, and what are the part numbers?
Two amperage options: 0.1A, ordered as GGC1/10, and 1.5A, ordered as GGC1-1/2. Both carry the same 250VAC rating, same glass body, and same clip-mount ferrule format, so you can stock one style across both circuit protection points.
3) Can I use a GGC fuse on a 480V control circuit?
No. The GGC fuse in these amperages is rated 250VAC, so it should not be applied above that. For higher-voltage control circuits you want a fuse rated for that system voltage, such as a Class CC type: the Littelfuse CCMR Series (CCMR040) is a Class CC fuse we carry, though it is time-delay rather than fast-acting.
4) Is a fast-acting fuse like the GGC right for a circuit with motor or transformer inrush?
No. The GGC is a fast-acting fuse, built to open quickly on overcurrent to protect sensitive electronics, instrumentation, and control circuits. Inrush from a motor or transformer primary will nuisance-blow it. For those loads use a time-delay fuse instead, such as the Littelfuse CCMR Series Class CC time-delay.
5) Can I replace an OEM glass fuse in a piece of equipment with a Mersen GGC?
If the existing fuse is a 1/4" x 1-1/4" glass ferrule fuse in a clip, fast-acting, at 250V or less, and the amp rating matches 0.1A or 1.5A, the GGC is a direct form-fit replacement. What you cannot change is the speed characteristic: if the original was a time-delay fuse, swapping in the fast-acting GGC will cause nuisance openings.
6) I am fusing a PowerLogic energy meter at 600V. Will a Mersen GGC work?
No. Use the Square D PowerLogic Energy Meter Fuse Pack, a set of three 0.5A 600V fuses built for that metering application. The Mersen GGC Series carries a 250VAC rating, so it is below the 600V requirement even though its 0.1A to 1.5A range brackets 0.5A. Keep the GGC for the 250VAC control and instrumentation circuits it is rated for.
7) How do I tell if a Mersen GGC fuse is blown without pulling it out of the panel?
The body is clear glass, so you can see the element. A broken or vaporized element is visible through the housing, which lets a technician check a fuse in a clip without removing it and metering it. That is the practical advantage of the glass body over a laminated or ceramic tube fuse.
8) Does the Mersen GGC fuse carry UL and CSA approvals for use in a commercial control panel?
The GGC Series is UL Listed and CSA Certified, which is what most facility and institutional spec writers require for overcurrent protection in control and instrumentation circuits. Voltage rating under UL is 250 V AC.
9) What is the difference between the Mersen GGC glass fuse and a Littelfuse BLF midget fuse?
Different body and format. The GGC is a 1/4" x 1-1/4" glass tube fast-acting fuse with ferrule ends for clip mounting. The Littelfuse BLF Series is a midget fast-acting fuse rated 250V with a laminated tube body, which is a larger physical envelope and will not fit 1/4 x 1-1/4 clips. Match the holder you already have in the panel.
10) I need a glass fuse in a higher amperage than 1.5A for the same size clip. What else do you stock?
The GGC options here stop at 1.5A. For higher-current glass fuses, Littelfuse AG-style glass tube fuses are an option we carry, including the AGA Series (AGA5 at 5A) and the AGU Series glass tube fuse. Confirm the holder length matches the AG size you pick, since AG designations cover several body dimensions.
11) Where is the Mersen GGC fuse made?
Country of origin is China. This matters for buyers with domestic-sourcing or origin-reporting requirements on purchase orders.
