Mersen ATM6 – Frequently Asked Questions

1) What amp ratings does the Mersen ATM midget fuse come in?
The ATM series runs 1A, 2A, 3A, 4A, 5A, 6A, 8A, 10A, 12A, 20A, 25A and 30A, ordered by the part number matching the rating (ATM1 through ATM30). All twelve share the same 600VAC/600VDC dual rating, fast-acting characteristic and 1.5 inch midget body, so stepping up or down an amp size does not change the holder you mount it in.
2) Will a Mersen ATM fuse fit a standard 13/32 x 1-1/2 midget fuse holder?
Yes. The ATM is a midget class fuse with a 1.5 inch body and ferrule terminals, so it drops into clip-style midget holders and blocks. Mounting is clip, not bolt-down, so you are pulling and replacing it by hand with the circuit dead.
3) Can I use the Mersen ATM on a DC circuit, like a solar or battery system?
Yes, the ATM is rated 600V on DC as well as 600V AC, which is unusual for a small midget fuse and is what makes it usable in converter, drive and battery-side circuits. Most midget fuses carry a much lower DC rating than their AC rating, so check the fuse you are replacing before assuming the swap works the other direction.
4) Is a fast-acting midget fuse the right choice for protecting a motor circuit?
No. The ATM is fast-acting, which means it clears quickly on overcurrent with no deliberate delay, so a motor's inrush at start will nuisance-blow it. Fast-acting is what you want ahead of semiconductors, power supplies, converters, instrumentation and control electronics, where the load draws steady current and the damage happens in milliseconds. For a motor branch you want a time-delay midget fuse instead.
5) What interrupting rating does the Mersen ATM have, and is it enough for a panel with high available fault current?
100 kA AC breaking capacity. That covers essentially any control panel or distribution point in an industrial or commercial building, and it is the number your panel's short circuit current rating calculation needs from the fuse. Frequency rating is 50/60 Hz, so it is fine on either supply.
6) How do I identify which Mersen ATM fuse I need to reorder?
The part number is ATM plus the amp rating, so an 8 amp fuse is ATM8 and a 30 amp is ATM30. Read the rating off the end cap or the body of the fuse you are pulling and match it. Voltage, class, length and speed are the same across the whole ATM range, so amperage is the only variable you have to get right.
7) What fuse should I use for the voltage sensing leads on a PowerLogic energy meter instead of a midget fuse?
For the metering leads on a PowerLogic energy meter, the Square D EMFP3 fuse pack is the matched part: it is a set of three rated 0.5A at 600V for that series. The Mersen ATM covers the load side of the same panel rather than the meter leads, in fast-acting midget class ratings from 1A through 30A at 600VAC/600VDC with a 100 kA AC breaking capacity. Buyers commissioning a metering cabinet often need both, one for the meter inputs and the ATM amperage that suits each protected branch.
8) What are the ferrules on the Mersen ATM fuse made of, and will they hold up in a humid or corrosive panel?
Tin-plated copper end caps, with a GMG insulating body between them. Tin plating over copper is what keeps the clip contact from oxidizing and running hot in damp mechanical rooms and outdoor enclosures, and it is the reason a fuse in a clip holder does not need retorquing the way a bolted connection does.
9) Are Mersen ATM fuses RoHS compliant for a spec that requires it?
Yes, the ATM midget fuse is RoHS compliant, which is what most institutional and government electrical specs are asking about when they flag hazardous substance restrictions on components.
10) How much does a Mersen ATM fuse weigh for shipping a panel spares kit?
About 0.017 lb each, so a full set of spares in every amp rating adds negligible weight to a truck stock or MRO crib. That is the practical case for stocking the whole ATM range rather than one or two ratings.
