Littelfuse JTD-090ID - Time-Delay Fuse 90A 600V (200kA Interrupt Rating)

Littelfuse JTD-090ID is a low-voltage time-delay fuse designed for circuit protection in industrial control systems. It features a 90A current rating and 600V AC/DC voltage rating, housed in a compact 10.3mm x 38mm ceramic body with tin-plated copper end caps for reliable conductivity. The fuse meets UL 248-14 and CSA standards for branch circuit protection, with a 200kA interrupting rating for high-fault conditions. Its time-delay characteristics make it ideal for motor circuits, transformers, and other inductive loads requiring inrush current tolerance.
