The MERSEN A4J100 is a 600V 100A Class J Fuse. Amp-Trap fast acting A4J fuses deliver excellent current limiting protection to a wide variety of applications. Their unique dimensions prevent the substitution of other fuses with lower voltage ratings, interrupting ratings, or current limiting capability.
This Mersen fuse is ideal for use in capacitors, loadcenters, panelboards, switchboards, bus duct, feeder circuits, circuit breakers, lighting, heating and general loads.
