Bussmann JCL-24R Class J Fast Acting Cartridge Fuse

The Bussmann JCL-24R is a Class J fast-acting cartridge fuse from Eaton Bussmann (Cooper Bussmann) designed for motor-circuit protection in industrial power systems. It is rated for 450 A and up to 5,080 V, and it is identified as an R-rated fuse, providing rapid interruption in fault and surge conditions to guard downstream equipment and wiring. The 24R model sits within Bussmann’s JCL family as a high-current, high-voltage, fast-acting solution for protecting motor circuits and is intended for use with compatible Bussmann fuse holders in medium- to high-voltage motor protection applications. Typical uses include safeguarding industrial motors and motor-driven equipment where fast fault clearance is essential, helping to minimize damage and downtime. This model is documented in Bussmann/Eaton catalogs and distributor listings as JCL-24R, confirming its role as a Class J fuse optimized for motor protection at elevated voltages.
