The Bussmann JKS-4 is a Class J time-delay fuse from the LIMITRON family, designed to provide reliable overcurrent protection for low-voltage industrial circuits. It features a 4A current rating and a 600V AC voltage rating, with a high 200kA interrupting capacity at rated voltage for robust short-circuit protection. The fuse is constructed as a single-barrel device with a compact body measuring 2.25 inches in length and 0.81 inches in diameter, weighing 0.095 lb, and is manufactured in Mexico. It complies with key industry standards, including UL 248-8 and CSA C22.2 No. 248-8, certified under guide JDDZ for Class J fuses. Typical applications include the protection of motor circuits, transformers, and feeder circuits where a time-delay characteristic is required to handle inrush currents.
