Mersen GGC1 – Frequently Asked Questions

1) Is the Mersen GGC a fast-acting or time-delay fuse?
Fast-acting. The GGC clears an overcurrent quickly rather than riding through it, which is what you want on electronic loads, instrumentation, and power supply outputs. If the circuit has an inrush surge at startup, a motor or a transformer primary, a fast-acting fuse will nuisance blow and you want a time-delay type instead.
2) How do I pick the right GGC amp rating to replace a blown fuse?
Read the rating off the old fuse cap or the holder label and match it exactly, then order the GGC with that number after it: a 4 amp becomes GGC4, a 10 amp becomes GGC10. Do not size up because it keeps blowing. A repeat blow on a fast-acting fuse means either a fault downstream or a load with startup inrush that needs a time-delay fuse instead. Also confirm the old fuse is 6.3x32mm and glass with ferrule ends, since the same amp rating exists in several body sizes that will not fit your clips.
3) Can a Square D PowerLogic EMFP3 energy meter fuse pack be used in place of a Mersen GGC fuse?
They are sized for different jobs. The Square D PowerLogic energy meter fuse pack is a set of three fuses rated 0.5A at 600V, supplied as a matched pack for metering circuits. The Mersen GGC is a single fast-acting glass fuse rated 250VAC in the 6.3x32mm ferrule size, ordered one amperage at a time across 1/4A through 25A. If the circuit is a 600V metering input, the PowerLogic pack is the part built for it; if it is a 250VAC electronic or control circuit taking a 6.3x32mm clip-mounted fuse, that is the GGC.
4) I need a half-amp fuse for a 600 volt metering circuit - is the Mersen GGC1/2 the right part?
The GGC1/2 is a 1/2A fuse, but the GGC series carries a 250VAC rating, so it is not the part for a 600 volt input. For metering at that voltage the Square D PowerLogic energy meter fuse pack covers 0.5A at 600V and comes as a set of three, which suits a three-phase meter where all legs are fused together.
5) What amp ratings does the Mersen GGC glass fuse come in?
Seventeen ratings across the GGC line, from 1/4A up to 25A: 1/4, 3/10, 4/10, 1/2, 1, 2, 2-1/2, 3, 4, 5, 6, 7, 8, 10, 15, 20 and 25 amps. The part number is the series plus the rating, so a 5 amp is GGC5 and a 2-1/2 amp is GGC2-1/2. Fractional ratings carry the fraction in the number, like GGC3/10.
6) Will a 250VAC glass fuse work on a 120V control circuit?
Yes. The 250VAC rating on the GGC is a maximum, not a target, so it is fine on 120V or 24V AC circuits. The rule runs one way only: never put it on a system above 250 volts. The voltage rating governs whether the fuse can safely break the arc, and the amp rating is what you match to the load.
7) Is a Square D PowerLogic meter fuse pack an alternative to the GGC?
Not a substitute. The Square D PowerLogic Energy Meter Fuse Pack is a 0.5A 600V set of three sold for metering circuits on PowerLogic equipment, so it is matched to that instrument, not to a general clip holder. If you are fusing a PowerLogic energy meter, use the meter fuse pack. For general supplemental protection in a control panel or power supply at 250VAC, the GGC in the amp rating your circuit calls for is the part.
8) Does the Square D PowerLogic fuse pack cover the low fractional amperages that the Mersen GGC does?
Only one point of it. The PowerLogic energy meter fuse pack is a fixed 0.5A rating sold three to a pack. The Mersen GGC spans the fractional range with individual 1/4A, 3/10A, 4/10A and 1/2A ratings and continues up through 25A, so if you are matching a specific low-amperage value on a 250VAC electronic circuit, the GGC is where those increments live.
9) Our panel has clip-style fuse holders - which of these fuses drops into them?
The Mersen GGC is built with ferrule terminals in the 6.3x32mm size and mounts by clip, so it seats in standard clip-style holders and the glass body lets you see whether the element has opened without pulling it. The Square D PowerLogic part is a fuse pack supplied as a set of three for energy meter service rather than a single loose ferrule fuse, so plan it around the meter it serves rather than around a general-purpose fuse block.
10) Why choose a glass body fuse over a ceramic one?
Glass lets you see the element. On the GGC you can hold it up and tell at a glance whether the wire is intact or the fuse has cleared, which cuts troubleshooting time in a panel full of holders. Ceramic bodies hide that, and are used where higher interrupting energy or arc containment matters. For electronic and control work at 250VAC, glass is the normal choice.
11) Is the Mersen GGC fuse RoHS compliant for electronic assemblies?
Yes, the GGC is built RoHS compliant with lead-free construction, so it can go into assemblies and finished equipment that have to hold a RoHS declaration. That matters if you are building or repairing OEM electronics rather than just servicing a panel.
12) Where is the Mersen GGC fuse normally used?
Control panel circuits, instrumentation, power supplies, and industrial or commercial electronic equipment, wherever a device needs supplemental overcurrent protection sized in single-digit amps. For MRO stock, the practical move is holding the ratings your building's panels actually use rather than the whole range, since the fuse body and holder are identical across all 17 ratings and only the number changes.
