Mersen AG30 – Frequently Asked Questions

1) Will a Mersen AG30 fuse fit a Class G fuse holder, and can I drop it into a Class CC or midget holder?
The AG30 is built to Class G rejection dimensions, so it seats in a Class G holder or block and the rejection feature keeps a differently rated fuse out. It will not fit a Class CC or midget clip, those are a different body size and rejection scheme. If your holder is Class CC, look at a Class CC time-delay fuse such as the Littelfuse CCMR Series instead.
2) Is the Mersen AG30 the right fuse for a motor or compressor circuit that trips on startup?
Yes, that is what the time delay element is for. The AG30 rides through the inrush of a motor or other inductive load during starting but still opens on a sustained overload, so a properly sized circuit stops nuisance-blowing. It is rated 30A at 480VAC. A fast-acting glass fuse like the Littelfuse AGU or BLF Series would open on that same inrush.
3) Can I use the Mersen AG30 on a 480V three-phase panel?
Yes. The AG30 carries a 480VAC rating, which covers 480V three-phase distribution, motor control centers and commercial HVAC gear. It is an AC-rated fuse, so do not apply it on a DC circuit. Using it below its voltage rating, on 240V or 208V for example, is fine.
4) What is the closest time-delay alternative to the Mersen AG30 for a motor circuit that uses Class CC fuse holders?
The Mersen AG30 is a Class G time delay fuse rated 30A at 480VAC with ferrule terminals, and Class G bodies use rejection dimensions that will not seat in a Class CC holder. For a Class CC block, the Littelfuse CCMR040 is a Class CC time-delay fuse rated 40A. Both share the time-delay characteristic suited to motor inrush, but they are different UL fuse classes and different ampere ratings, so confirm the holder class and the required ampere rating against the equipment nameplate before ordering either.
5) Can a glass tube fuse be used in place of the Mersen AG30?
No. The Mersen AG30 is a Class G rejection-type fuse with a 480VAC rating, ferrule terminals and 100 kA breaking capacity for commercial and industrial branch circuits. Glass tube fuses such as the Littelfuse AGA5 in the AGA series or the Littelfuse AGU series are small glass tube devices used in low-power and automotive style holders. They do not carry Class G rejection dimensions and will not fit a Class G fuse block, so they are not a substitute for the AG30.
6) What fault current can the AG30 interrupt on a high available-fault service?
100 kA is the maximum breaking capacity on the Mersen AG30, so it handles the available fault current on most commercial and industrial services fed from a large transformer. That number is what your engineer checks against the calculated short circuit current at the panel.
7) What terminal style does the Mersen AG30 have, and does it clip into a standard fuse block?
Ferrule terminals, tin-plated copper, so it presses into spring clips or a Class G fuse block rather than bolting down. No lugs or bolt holes. The tin plating is what keeps the clip contact from corroding and running hot over time.
8) I need to order replacement fuses for a building. What exactly do I ask for?
Ask for Mersen AG30. That is the manufacturer part number, an Amp-Trap Class G time delay fuse, 30A at 480VAC with ferrule ends. There are no finish or length options to specify, the AG30 is a single configuration, so quantity is the only variable when you standardize a stockroom on it.
9) What is the difference between the Mersen AG30 and a midget fast-acting fuse like the Littelfuse BLF?
The Mersen AG30 is a Class G time delay fuse rated 480VAC at 30A, so it rides through motor and transformer inrush before opening on a sustained overload. The Littelfuse BLF series is a midget fast-acting fuse rated 250V with a laminated tube body, which clears quickly and is aimed at circuits that do not see inrush, such as control and resistive loads. Choose the AG30 where the load starts under inrush and the panel is a 480V system, and a fast-acting midget where the circuit voltage is 250V or less and fast clearing is wanted.
10) Is the Mersen AG30 suitable for metering circuits, or is a dedicated meter fuse pack better?
The Mersen AG30 is a 30A branch and equipment protection fuse at 480VAC with a 100 kA breaking capacity, sized for motor and distribution loads rather than instrument circuits. For potential leads on a power meter, the Square D PowerLogic Energy Meter Fuse Pack is a set of three fuses rated 0.5A at 600V, which is the low ampere, high voltage rating a metering circuit calls for. Use the AG30 on the load side feeder and the metering pack on the meter potential taps.
11) Is the Mersen AG30 RoHS compliant for a spec job?
Yes, the AG30 is RoHS compliant, which is usually what a facility or government procurement spec is asking for on electrical components.
12) What is the AG30 fuse body made of and will it hold up in a hot panel?
The body uses GMG insulating material, which is what Mersen specifies for sustained service in industrial panels and motor control centers. It is a melamine glass type body rather than the glass tube used on small automotive and appliance fuses like the Littelfuse AGA and AGU series.
