A3T1100 - 1100 Amp Fuse

A3T1100 - 1100 Amp Fuse

The A3T1100 is designed to protect high-amperage circuits quickly and safely. It reacts immediately to overloads or short circuits, helping prevent equipment damage. The knife-blade design makes installation easy, and the non-indicating style keeps things straightforward. Even though it handles 1100 amps, it’s compact—just 4 inches tall and 2.5 pounds—so it fits neatly in most panels. With a 200 kA interrupting rating at 300 V.AC, it’s a dependable choice for industrial and commercial setups.
