A2D100R Fuse -Time-Delay - Class RK1

250 Volt - 100 Amp - 200kA I.R. AC - 5 Pack - Mersen


This Mersen 250-volt A2D100R time-delay fuse provides IEC Type 2 "no damage" protection to existing mains, feeders, and branch circuits serving motor and non-motor loads. Providing maximum short circuit protection to prevent damage to motor starters, switches, and other circuit components by opening fast enough under extreme fault conditions, this 5-amp fuse also provides the time-delay needed for motor in-rush currents. The fuse features Amp-Trap 2000 technology that minimizes up to 200kA of let-thru current that flows downstream and a SmartSpot indicator, which displays red when the fuse is open, both of which allow you to reduce downtime that can adversely affect productivity and profits. The fuse can also be used to replace 250V Class H, K or RK5 fuses already installed. Sold only by the pack of 5.
