BUSSMANN Effective March 2017 Technical Data 10289 Supersedes December 2015 SERIES Class H(K), J and R modular ferrule fuse blocks Features and benefits: 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. DIN-Rail and panel mount versatility allows one product to be used for multiple applications with lower inventory cost. Save panel space with the smallest width dimension on the market. Standard clip reinforcing springs improve temperature rise performance while maintaining reliable surface contact between the fuse ferrule and clip over the blocks service life. Optional see-through, IP20 finger-safe Product description: covers enhance safety with lock-out/tag-out capability. HM Class H(K), JM Class J and RM Class R modular ferrule fuse blocks for fuses up to 60 Optional open fuse indication on covers amps. speeds troubleshooting.
