Shawmut AJT110 Industrial Time Delay Protective Fuse

The Shawmut AJT110 is a 110 A Class J time-delay protective fuse designed for industrial power protection, rated up to 600 VAC and up to 500 VDC in applicable variants. Built on Mersen/Ferraz Shawmut’s Amp-Trap 2000 platform, it delivers time-delay protection that handles harmless inrush currents while interrupting faults quickly. The cylindrical fuse uses ferrule terminations and is available with SmartSpot visual indication in certain configurations for status checks. Its dimensions are about 146.1 mm in length (5-3/4 in) and 41.3 mm in diameter, and it is UL 248-8 listed for general-purpose Class J protection in input, power, and distribution circuits across motors, drives, panels, and other industrial equipment. With a design optimized for applications with startup surges, the AJT110 provides reliable protection without nuisance openings and helps prevent damage to downstream equipment during faults.
