Product Description
The A4J80 is an 80 Amp, 600 Volt (AC) / 300 V (DC) fast-acting, current-limiting fuse from Gould Shawmut’s Amp-Trap® A4J series. It’s built for industrial and commercial applications where reliable protection against overloads and short circuits is needed. With high interrupt capacity and precise current-limiting, it safeguards panelboards, feeders, lighting, and general-purpose loads with minimal let-through energy, helping protect circuits and equipment from damaging fault currents.
