Mersen Amp-Trap 2000 A6D-R Class RK1 Time-Delay Ferrule Fuse

Mersen Amp-Trap 2000® A6D-R time-delay fuses are Class RK1 ferrule-terminal fuses rated 600 V that deliver IEC Type 2 "no damage" protection to mains, feeders, and branch circuits serving both motor and non-motor loads. This family is available across a Motor FLA range from 0.1A to 6A (0.1A, 1.25A, 1.6A, 2A, 2.25A, 2.5A, 3A, 6A), so the correct amp rating can be matched to the specific motor or circuit being protected while every option shares the same Class RK1 time-delay construction, 600 V rating, and 200 kA interrupting capacity. Built with a PolyTube body and tin-plated copper terminals for clip mounting, these fuses open fast under extreme fault conditions for maximum short-circuit protection while still providing the time-delay characteristic needed to ride through motor in-rush currents. A6D-R fuses are a direct replacement for older 600V Class H, K, or RK5 fuses already installed in the field, allowing an upgrade in protection without reworking existing fuse holders.

  • Fuse Class: Class RK1 construction for IEC Type 2 "no damage" short-circuit protection.

Mersen A2D2-1/2R – Frequently Asked Questions

1) Can I drop Mersen A6D-R fuses into my existing Class H, K or RK5 fuse holders?
Yes. The Amp-Trap 2000 A6D-R is a direct replacement for older 600V Class H, K or RK5 fuses already in the field, so you upgrade the protection without reworking the existing fuse clips or holders. The rejection-style Class RK1 body still fits standard non-rejection RK clips, and the terminals are tin-plated copper ferrules for clip mounting.
2) What amp ratings do the Mersen A6D-R ferrule fuses come in?
The A6D-R time-delay ferrule family covers motor FLA from 0.1A up to 6A: 0.1A, 1.25A, 1.6A, 2A, 2.25A, 2.5A, 3A and 6A. Order by the part number that matches the rating, for example A6D1-1/4R for 1.25A, A6D2-1/4R for 2.25A, A6D3R for 3A and A6D6R for 6A. Every rating shares the same 600V, 200kA, Class RK1 time-delay construction.
3) Will a time-delay RK1 fuse hold on motor starting current, or will it nuisance-trip?
Time-delay is the point of the A6D-R. It rides through motor in-rush without opening, then clears fast under a true short circuit. That combination is what gives IEC Type 2 no-damage protection to the starter and contactor, so the equipment stays serviceable after a fault instead of needing replacement.
4) Is the Littelfuse BLF midget fuse an alternative to the Mersen A6D-R for a motor branch circuit?
They are not interchangeable. The Littelfuse BLF is a midget fast-acting fuse rated 250 V with a laminated tube body, so it opens quickly and is aimed at circuits that do not see inrush. The Mersen A6D-R is a Class RK1 time-delay fuse rated 600 V with a PolyTube body and a 200 kA interrupting rating, built to ride through motor in-rush without nuisance opening. For a motor starter or motor branch circuit on a 600 V system, the time-delay A6D-R is the correct characteristic; the fast-acting BLF suits lower-voltage control and non-inductive loads.
5) Is a 200kA interrupting rating enough for my service entrance?
The A6D-R carries a 200kA AC interrupting rating, which is the highest commonly specified for low-voltage distribution and covers available fault current at essentially any commercial or industrial service. It is rated 600V and suits 50/60 Hz systems, so it works on mains, feeders and branch circuits alike.
6) Should I use a Class RK1 ferrule fuse or a Class CC fuse for small motor branch protection?
It comes down to what the holder is prepped for. The Mersen A6D-R is a ferrule-terminal Class RK1 that fits standard R-class clips and is the right call when you are upgrading existing H, K or RK5 fuse blocks in place. If the equipment is built around a compact Class CC block instead, you need a CC fuse such as the Littelfuse CCMR Series time-delay, which ZenSupply also carries in 40A. The two classes are not physically interchangeable.
7) Can I substitute a glass tube fuse for a Mersen A6D-R?
No. Glass cartridge fuses like the Littelfuse AGA or AGU series are low-voltage electronic and automotive style parts, not 600V branch-circuit protection. The A6D-R is a 600V Class RK1 with a 200kA interrupting rating and a PolyTube body built for panel and motor-circuit duty. Substituting a glass fuse into a 600V motor circuit is not a valid swap.
8) Will a Littelfuse AGA or AGU glass fuse work where a Mersen A6D-R is specified?
No. The Littelfuse AGA series, such as the AGA5 5 A glass fuse, and the AGU series glass tube fuse are small glass-body automotive and appliance style fuses. The Mersen A6D-R is a Class RK1 time-delay fuse with a PolyTube body, tin-plated copper ferrule terminals, and a 200 kA interrupting rating at 600 V for mains, feeders, and branch circuits in commercial and industrial panels. The glass fuses do not carry the Class RK1 construction or the clip-mount ferrule dimensions the A6D-R holders are built around, so they are not a substitute in a fused disconnect or motor starter.
9) For a 600V metering circuit, should I order the Mersen A6D-R or the Square D PowerLogic fuse pack?
Match the fuse to the load, not just the voltage. The Square D PowerLogic energy meter fuse pack is supplied as a set of three at 0.5 A, 600 V, sized for the voltage-sensing leads of a PowerLogic meter. The Mersen A6D-R is a Class RK1 time-delay fuse rated 600 V with a 200 kA interrupting rating, offered across motor FLA ratings from 0.1 A to 6 A for motor and non-motor branch, feeder, and main protection. If the job is fusing the potential taps on a PowerLogic meter, the Square D pack is the matched set; if it is protecting a motor starter or branch circuit through existing ferrule clips, the A6D-R is the one.
10) Are Mersen A6D-R fuses RoHS compliant for a spec job?
Yes, the A6D-R Amp-Trap 2000 time-delay fuses are RoHS compliant, which covers most institutional and government procurement requirements on materials content.
11) What is the fuse body made of and will it hold up in a hot panel?
The A6D-R uses a PolyTube body with tin-plated copper ferrule terminals. The plated terminals resist corrosion at the clip contact, which is where heating and bad connections usually start in an older fuse block.
