Mersen A6D60R – Frequently Asked Questions

1) Can a Mersen Amp-Trap 2000 A6D RK1 fuse be used on a 600V DC circuit, like battery storage or solar?
Yes. The Amp-Trap 2000 Class RK1 time-delay fuse is rated 600VAC and 600VDC, so it covers both AC and DC service, and the description calls out battery storage and renewable energy systems among its applications. On AC it carries a 200kA breaking capacity and is rated for 50/60 Hz systems.
2) Will a time-delay RK1 fuse hold in on motor inrush, or will it nuisance-blow?
Time delay is exactly why you'd pick this one. The A6D is a time-delay characteristic fuse, so it rides through temporary overloads such as motor starting inrush while still clearing sustained overcurrent. That's why it's spec'd into motor control centers, VFDs and commercial HVAC. If you want a fast-acting fuse instead, for semiconductor or non-inductive loads, this is the wrong characteristic.
3) Will a Class RK1 fuse fit my existing Class R fuse clips?
The A6D mounts in clips and uses ferrule terminals with tin-plated copper. Class R fuses share a common mounting dimension within a given amp range, and RK1 will seat in a rejection-style Class R block. Going the other direction, an RK5 fuse will also fit an RK1 holder, but RK1 gives you the tighter current-limiting let-through. Match the amp rating and the 600V class of your block.
4) Can a Littelfuse CCMR040 Class CC fuse be used in place of the Mersen A6D60R RK1 time-delay fuse?
No. The Mersen Amp-Trap 2000 A6D60R is a Class RK1 time-delay fuse rated 600VAC/600VDC with ferrule terminals and clip mounting, so it seats in an R-class fuse clip. The Littelfuse CCMR040 is a Class CC time-delay fuse in a 40A rating, a much smaller midget-style body on a different rejection footprint. Both are time-delay, but the class and holder are not interchangeable - a 60A RK1 clip will not accept a Class CC fuse, and the CCMR040 tops out at 40A.
5) What is the difference between the Mersen Amp-Trap 2000 RK1 fuse and a Littelfuse BLF midget fast-acting fuse?
Two different jobs. The Amp-Trap 2000 A6D series is a Class RK1 time-delay fuse rated 600VAC/600VDC with 200kA breaking capacity, built to ride through motor inrush while clearing sustained overcurrent, and it carries SmartSpot blown-fuse indication. The Littelfuse BLF is a midget fast-acting fuse rated 250V in a laminated tube body, which opens quickly with no intentional delay. For a motor circuit or VFD feed you want the time-delay RK1; for a control or semiconductor circuit that needs fast clearing at 250V, the fast-acting midget is the different animal.
6) What amperages does the Mersen A6D RK1 fuse come in?
Two ratings are offered in the A6D line: 60A (A6D60R) and 600A (A6D600R). Both are 600VAC/600VDC Class RK1 time-delay with ferrule terminals and clip mounting.
7) How do I tell if a Mersen Amp-Trap 2000 fuse is blown without pulling it out?
It carries the SmartSpot indication system, a visual indicator on the fuse body that shows fuse status so you can spot an opened fuse during a walk-down instead of testing each one. That's the practical difference between this and a plain RK1 fuse on a maintenance route.
8) Can I use a midget or glass tube fuse instead of this RK1 for equipment protection?
Not for the same duty. The Littelfuse BLF Series is a midget fast-acting fuse rated 250V, and the AGA and AGU series are small glass tube fuses. Those are control-circuit and low-voltage device protection. The Amp-Trap 2000 A6D is a 600VAC/600VDC power fuse with 200kA breaking capacity for feeder, motor and switchgear duty. Don't substitute a 250V midget into a 600V branch circuit.
9) Is 200kA enough interrupting rating for a service entrance or MCC with high available fault current?
200kA is the AC maximum breaking capacity on the Amp-Trap 2000 RK1, which covers available fault currents well above what most industrial services see. Combined with the RK1 current-limiting characteristic, the fuse clears the fault in less than a half cycle and cuts the let-through energy reaching downstream gear.
10) Will a Littelfuse AGU or AGA glass fuse work as a substitute for the Mersen A6D600R?
No. The Mersen A6D600R is a 600A Class RK1 fuse rated 600VAC/600VDC with a PolyTube insulating body, tin-plated copper ferrule terminals and clip mounting for branch and feeder protection. The Littelfuse AGU and AGA5 are small AG-style glass tube fuses - the AGA5 is a 5A rating - used for low-current electronic and automotive-style circuits. They share the ferrule-tube shape visually but are nowhere near the amperage, voltage class or interrupting duty of an RK1 feeder fuse.
11) I need fuses for a PowerLogic energy meter - is the Mersen Amp-Trap 2000 RK1 the right part?
No, that is a different application. Metering voltage taps use small low-amperage fuses such as the Square D PowerLogic energy meter fuse pack, supplied as a set of three at 0.5A 600V. The Mersen Amp-Trap 2000 A6D is a Class RK1 time-delay power fuse offered in 60A and 600A ratings for motor branch circuits, distribution panels and switchgear. Use the metering fuse pack on the meter's potential leads and the RK1 on the power circuit it is measuring.
12) My panel calls for a Class CC time-delay fuse in a small amperage - what changes if I try to standardize on the Mersen Amp-Trap 2000?
The block or holder changes with it. The Amp-Trap 2000 A6D is Class RK1 with ferrule terminals and clip mounting, supplied in 60A and 600A ratings at 600VAC/600VDC. A Class CC circuit like one using the Littelfuse CCMR040 at 40A uses a rejection-style CC holder that RK1 bodies do not fit, and 40A is below the smallest A6D rating anyway. Standardizing on RK1 means changing the fuse block and re-checking the branch circuit protection sizing, not just the fuse.
13) Will these fuses corrode in a humid or washdown electrical room?
The terminals are tin-plated copper ferrules, which resist corrosion at the clip contact, and the body is a PolyTube insulating tube. Clean, tight clip contact still matters: a corroded or relaxed clip runs hot regardless of the fuse plating.
