Mersen GAB15 – Frequently Asked Questions

1) What amp ratings does the Mersen GAB fuse come in?
Fourteen ratings across the series: 1A, 1-1/2A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 10A, 12A, 15A, 20A and 25A, ordered as GAB1 through GAB25 (the 1-1/2 amp is GAB1-1/2). One part number per rating, so specify the amperage when you order.
2) Is the Mersen GAB rated for a 250 volt circuit?
250VAC is the rating, and the series is AC only. That covers 120V and 208/240V control and equipment circuits. Do not apply it on a DC circuit or above 250 volts AC, since no DC rating is carried for this series.
3) Is a Mersen GAB fuse a branch-circuit fuse I can use as the main protective device?
No. The Mersen GAB is classified as a supplemental fuse, intended for protection downstream of the branch-circuit device rather than as the branch-circuit protection itself. Where the drawing calls for a branch-circuit class fuse, the Littelfuse CCMR series is a Class CC fuse, such as the CCMR040 at 40A. A common panel build uses a Class CC fuse at the branch and GAB fuses on the control and instrumentation taps behind it.
4) I need time-delay protection for a motor circuit, not fast-acting. What do I use instead of a Mersen GAB?
The Mersen GAB is a fast-acting supplemental fuse, built to interrupt quickly and protect sensitive electronic circuits, so it is the wrong characteristic for a load with motor inrush. For that, the Littelfuse CCMR series is a Class CC time-delay fuse, offered in ratings such as the CCMR040 at 40A, and it will ride through starting current. Keep the GAB for control-circuit and instrumentation protection downstream, where the fast-acting curve is what you want.
5) What is the closest equivalent to a Mersen GAB fuse in a midget fast-acting fuse?
The Littelfuse BLF series is the nearest match on operating characteristic: it is a midget fast-acting fuse rated 250V, the same voltage class as the Mersen GAB at 250VAC. The difference is body construction. The GAB uses a ceramic body in the 6.3x32mm Size 6 format, while the BLF uses a laminated tube. If the holder is clipped for 6.3x32mm ferrule ends, the GAB drops in; a midget fuse body is a different envelope and needs a holder cut for it, so confirm the clip spacing before you substitute either direction.
6) Can a Littelfuse AGA or AGU glass fuse replace a Mersen GAB fuse?
Not as a like-for-like. The Littelfuse AGA series, such as the AGA5 at 5A, and the Littelfuse AGU series are glass-body fuses; the Mersen GAB is a ceramic-body fuse. Ceramic is the construction chosen where arc extinction and thermal performance under fault conditions matter, which is why the GAB is specified for industrial control panels and equipment protection. A glass AG-style fuse also uses a different body size than the GAB's 6.3x32mm Size 6 envelope. Use the GAB where the panel legend calls for a ceramic 6.3x32mm fuse and keep the glass AG fuses to holders built for them.
7) What is the difference between a ceramic fuse like the Mersen GAB and a glass tube fuse?
The GAB uses a ceramic body, which handles heat better and contains the arc more effectively under a fault than glass. A glass body, like the Littelfuse AGA and AGU Series glass tube fuses, lets you see the blown element, which makes troubleshooting faster on a bench or in a serviceable panel. If the circuit is in a hot enclosure or you want the arc contained, take the ceramic; if visual diagnosis matters more, a glass tube is the reason people still buy it.
8) How long is a Mersen GAB fuse?
1.25 inches long in the 6.3x32mm Size 6 body, with ferrule ends. That length is what has to clear between your holder clips, and it is the same across the amp ratings in the series.
9) Is the Square D PowerLogic energy meter fuse pack the same thing as a Mersen GAB fuse?
They serve different jobs. The Square D PowerLogic energy meter fuse pack is a set of three fuses rated 0.5A 600V, sold for the voltage-sensing leads on a PowerLogic energy meter. The Mersen GAB is a 250VAC fast-acting supplemental fuse family in the 6.3x32mm ceramic format, covering ratings from 1A up to 25A for general control and equipment protection. If you are fusing meter potential taps on a 600V system, the GAB's 250VAC rating does not cover it; if you are protecting a control circuit or instrumentation load at 250VAC or less, the GAB is the family to size from.
10) Is the Mersen GAB fuse RoHS compliant for a spec job?
Yes, the GAB Series is RoHS compliant, which is what most institutional and government specs are asking for on electronic components. That is the compliance claim carried on the series.
11) What fuse should I stock for HVAC and lighting control panels across a building?
The Mersen GAB Series is a reasonable standardization choice for that work: one 6.3x32mm ceramic body across fourteen amp ratings from 1A to 25A, all 250VAC fast-acting, all clip-mount. Standardizing on the body size means one holder type and one set of spare clips, and you carry the ratings your panels actually use rather than several formats.
