Up to 400 A Class J ferrule and
knifeblade power distribution fuse blocks
Features and benefits:
•
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.

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.
