LittleFuse JTD090ID is a 600VAC/300VDC, 90A Class J dual-element, time-delay fuse designed for superior protection of motor circuits, transformers, and other inductive loads against short circuits and sustained overloads. It features a compact 2.25" x 1.56" x 1.56" body with a rejection-style ferrule construction for secure mounting in Class J fuse blocks, and it complies with UL 248-8 and CSA standards for branch circuit protection. This fuse offers a high interrupting rating of 200kA RMS symmetrical at 600VAC, making it suitable for industrial control panels, motor starter disconnects, and feeder circuits where high fault currents are present. The dual-element design combines a low-resistance overload element with a fast-acting short-circuit element, providing both time-delay for motor starting inrush and excellent current limitation for component protection.
