100A to 400A Class J Power Distribution Fuse Blocks

Save space, time and money with the new power distribution fuse block

New Class J fuse block features power distribution capability

This patented design simplifies your panel layout and uses up to 50% less panel space. Additionally, it lowers inventory costs while reducing installation time and labor by 33%.

Furthermore, this design uses fewer wire connections, reducing watts loss and overall operating temperature when compared with traditional fuse block/ power distribution block solutions.

Features and benefits:

  • Combination power distribution block and fuse block reduces wire connections and total panel components, using 50% less panel space and reducing installation time and labor by 33%.
  • A 200kA withstand rating helps achieve a higher assembly shortcircuit 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.
