Cooper Bussmann JM60030-1CR Fuse Block 30A 1 Pole

The JM60030-1CR is a Bussmann modular fuse block (Eaton Bussmann series) designed for Class J fuses, delivering 30 A protection in a single-pole, 600 V system configuration. It accepts J-series fuses and uses box-lug terminations for robust connections, with mounting options including 35 mm DIN rail or panel mounting for flexible installation. The block is rated for copper conductors 14 AWG to 2 AWG or aluminum conductors 8 AWG to 2 AWG, accommodating a range of wiring in control panels and equipment enclosures. Its open-block design allows easy fuse access and straightforward replacement, with covers sold separately (one cover per pole). Physical footprint measures roughly 3.4 in in length, 1.1 in in width, and 2.3 in in height, making it a compact choice for space-constrained applications where a dedicated 30 A Class J fuse per circuit is required. Common applications include industrial control panels, OEM equipment, and electrical enclosures that rely on reliable single-pole protection in 600 V Class J fuse systems.
