Technical Data 10192 Effective June 2016 Supersedes January 2014 Up to 400 A Class J ferrule and knifeblade power distribution fuse blocks Features and benefits: 30 and 60 amp modular ferrule blocks. 100, 200 and 400 amp modular knifeblade blocks. • Combination power distribution block and fuse block reduces wire connections and total panel components, using up to 65 percent less panel space and reducing installation time and labor by an average of 33 percent when compared with traditional fuse block/power distribution block solutions. • A 200,000 amp withstand rating helps achieve a higher assembly short-circuit current rating (SCCR) for compliance with NEC® sections 110.10, 409.110(4), 409.22, 440.4(B), 670.3(A)(4) and 670.5. • Optional see-through cover enhances safety with IP20 finger-safe protection, lockout/tagout capability and open circuit indication. • Available in 1-, 2- and 3-pole configurations to meet stocking requirements. • To reduce inventory, assembly time and labor, modular single-pole blocks snap-together for tool-less assembly of multiple poles at point of use. • Blocks rated up to 60 amps feature DIN-Rail and panel mount versatility, which allows one product to be used for multiple applications without incurring additional inventory cost. Catalog symbols: • JM60030-_MW_ • JM60060-_MW_ • JM60100-_MW_ • JM60200-_MW_ • JM60400-_MW_ Description: Bussmann® series Class J fuse block features power distribution capability. This patented design simplifies panel layouts and uses up to 65 percent less panel space. Additionally, it lowers inventory costs while reducing installation time and labor by an average of 33 percent. Furthermore, this design uses fewer wire connections, reducing watts loss and overall operating temperature of the panel.
