Shawmut AJT100 Class J Time Delay High Current Fuse

Shawmut AJT100 is a 100 A, 600 V Class J time-delay fuse from Mersen (formerly Ferraz Shawmut). It protects power circuits up to 600 V by tolerating short-duration inrush currents while quickly interrupting sustained faults, making it suitable for motor drives, power distribution panels, and industrial controls. This UL/CSA-listed Class J device is designed for use in standard AJT fuse blocks and is part of the AJT series' reliable time-delay protection family. With a 100 A rating and 600 V rating, the AJT100 provides a precise protection profile for systems where transient overloads are common but fault current must be rapidly cleared to prevent damage.
