Mersen AG30 – Frequently Asked Questions

1) What amp ratings does the Mersen AG Class G time delay fuse come in?
Three ratings: 30A (AG30), 40A (AG40) and 60A (AG60). All are Class G ferrule fuses rated 480VAC.
2) Will a Mersen AG fuse fit my existing Class G fuse holder?
It will if the holder is Class G. The AG is a ferrule-terminal fuse with clip mounting, and Class G is a size-rejecting design, so the body length is matched to the amp rating and only seats in a Class G clip sized for that rating. Class G holders won't take midget, Class CC or glass tube fuses, and vice versa.
3) Can I use a Class G time delay fuse on a motor circuit without it blowing on startup?
That's what the time delay characteristic is for. The AG allows the temporary inrush of a motor start to pass while still clearing sustained overloads and short circuits. Mersen lists motor control centers, commercial HVAC, and pump stations among its applications. For straight resistive or lighting loads a fast-acting fuse is the better match.
4) Is the Mersen AG rated for a 480V three phase panel?
Yes, the AG series carries a 480VAC UL voltage rating and works at 50/60 Hz, which covers commercial and industrial three-phase distribution. It is an AC-only fuse, so do not apply it on a DC circuit.
5) Is a Littelfuse AGU or AGA glass fuse the same thing as a Mersen AG Class G fuse?
No, despite the similar AG designation. The Littelfuse AGA Series AGA5 and the AGU Series are glass tube fuses, while the Mersen AG30, AG40 and AG60 are Class G time delay fuses rated 480VAC with tin-plated copper ferrule terminals and a GMG insulating body. The Mersen parts are branch-circuit protection fuses for distribution panels and motor control centers, not small glass-tube automotive or appliance fuses.
6) Can a Littelfuse CCMR040 be used in place of a Mersen AG40 Class G fuse?
No. The Mersen AG40 is a Class G time delay fuse rated 480VAC with ferrule terminals and a 2.25 in body, while the Littelfuse CCMR040 is a Class CC time-delay fuse at 40A. Class G and Class CC use different dimensions and rejection features, so the holder clips for one will not accept the other. Match the fuse class stamped on the block or holder before ordering.
7) What is the interrupting rating on the Mersen AG Class G fuse?
100 kA AC breaking capacity. That matters when your available fault current at the panel is high; the fuse has to be rated at or above the calculated short circuit current at its point of application.
8) Is the Mersen AG the right fuse for refrigeration and food service equipment?
Yes, Mersen lists food service and refrigeration systems along with commercial HVAC and building services among the applications for these Class G time delay fuses. The time delay handles compressor inrush, and the 30A, 40A and 60A ratings cover most packaged equipment circuits.
9) I need a fast-acting fuse instead of a time delay one for a 250V control circuit. What should I look at?
The Mersen AG Class G fuses are time delay, sized to ride through motor inrush at 480VAC. For a fast-acting part on a 250V circuit, the Littelfuse BLF Series is a midget fast-acting fuse rated 250V with a laminated tube body. Use the fast-acting characteristic where you want the quickest clearing on a non-inrush load, and keep the time delay Class G where motor starting current is present.
10) Will a Mersen AG30 work as the fuse in a Square D PowerLogic energy meter?
No. Metering fuse packs are a different animal: the Square D PowerLogic Energy Meter Fuse Pack is a set of three 0.5A 600V fuses for metering voltage inputs. The Mersen AG30 is a 30A Class G time delay fuse at 480VAC intended for branch circuit and motor load protection. Use the meter manufacturer's fuse pack for the metering taps and reserve the AG Class G fuses for the load side.
11) What is the AG fuse body made of, and is it RoHS compliant?
The body is GMG insulating material with tin-plated copper ferrule terminals, and Mersen lists the fuse as RoHS compliant.
