A4J Class J Power Fuses

Mersen A4J Class J Power Fuses provide excellent current-limiting protection to numerous applications. These fuses have unique dimensions that prevent the substitution of other fuses with lower ratings, interrupting ratings, or current-liming capability, providing additional protection against mismating. Constructed with a fiberglass body, dimensional stability is provided in harsh industrial environments, and the easy-to-read imprint label allows for quick recognition and replacement. Mersen A4J Class J Power Fuses are suitable for capacitors, load centers, switchboards, circuit breakers, feeder circuits, and panelboards.
