Littelfuse JTD-045 - Time-Delay Fuse 45A 600V (100kA AIC)

Littelfuse JTD-045 is a low-voltage time-delay fuse designed for circuit protection in industrial control systems. It features a 600V AC/DC voltage rating and a 45A current rating, providing reliable overcurrent protection in demanding environments. The fuse is constructed with a durable ceramic body and tin-plated copper end caps for optimal conductivity and heat resistance. It complies with UL/CSA standards and is rated for use in applications up to 100,000 AIC (Ampere Interrupting Capacity). Typical applications include motor control centers, transformers, and power distribution equipment where time-delay characteristics are required to handle inrush currents.
