A4J110 - 110 Amp Fuse

A4J110 - 110 Amp Fuse

The Mersen A4J110 Amp-Trap® Class J Fast-Acting Fuse is built to protect your high-current circuits without any guesswork. Rated at 110 amps and suitable for 600VAC and 300VDC, it reacts quickly to overloads and short circuits, helping keep your equipment safe and reduce downtime. Its blade-style terminals and unique size make sure only the correct fuse fits, so accidental substitutions with lower-rated fuses aren’t a problem.

With a sturdy GMG body and brass alloy terminals, the A4J110 offers reliable conductivity and long-lasting performance, even under high fault-current conditions.
