Bussmann JM60400-1MW26 Power Distribution Fuse

The Bussmann JM60400-1MW26 Modular Power Distribution Fuse Block is a 600 V, 400 A Class J power distribution unit that blends a fuse holder with a distribution block into a single, panel-mount assembly for compact protection in industrial control panels. This 1-pole configuration provides two line terminals and six load terminals per pole, with line-side connections rated for two conductors from 6 AWG up to 350 MCM copper or aluminum and load-side terminals rated for six conductors up to 14 AWG copper or 8 AWG aluminum. As part of the PDFB family, the JM60400-1MW26 reduces wiring and panel components while delivering 200 kAIC short-circuit protection and box-lug terminations suitable for panel mounting in 600 V systems. Typical applications include industrial machinery control panels and power distribution cabinets where a single unit protects multiple circuits with a shared supply. Variants exist in the JM60400 family, including a 3-pole JM60400-1MW26-3 configuration for multi-pole installations.
