Technical Data10488
Effective February 2016
Class J modular ferrule and knifeblade
fuse blocks
Knifeblade fuse blocks from 100 to 600 amps
feature phase barriers between poles for additional
safety with up to four mounting holes per pole
increase installation flexibility. All knifeblade blocks
meet UL creep and clearance requirements for
Industrial Power Circuits (UL 508 and UL 845).
Additionally, the 200 to 600 amp blocks meet the
higher UL creep and clearance requirements for
Power Distribution Standards (UL 98, UL 67, UL
489, UL 891 and UL 869A)
All blocks have optional IP20 finger-safe high
clarity, see-through covers for inspecting wire
terminations or thermography measurements
without removal. All covers enhance safety by
featuring probe holes for easier, safer testing
and a lockout/tagout capability. These covers
also have optional open fuse indication to speed
troubleshooting.
Easy circuit identification is available for 30 and
60 amp blocks and covers with universal marker
labels.

Agency information
•
These fuse blocks feature a standard fuse
clip reinforcing spring for enhanced electrical
contact between the blcok and fuse. All blocks
are available as single-pole versions that snap
together for the required number of poles, or as
factory configured 2-, and 3-pole versions to meet
stocking requirements.
The modular design permits reducing inventory,
assembly time and labor with tool-less assembly
of multiple poles at point of use.
Ferrule fuse blocks up to 60 amps save panel
space with the smallest width dimension on the
market and feature DIN-Rail and panel mount
versatility so that one product can be used for
multiple applications with lower inventory cost.

Modular Class J ferrule and knifeblade fuse blocks
30 and 60 amp ferrule fuse blocks have DIN-rail and panel mounting capability,
the modular designs allows blocks toand snap together for the desired number
of poles. They accept optional snap-on covers for IP20 finger-safe protection and
feature a lockout/tagout to improve electrical safety.
On blocks rated from 100 to 600A, the optional covers can be completely removed
for servicing or simply hinged open.
100 to 600 amp knifeblade fuse blocks are panel mount with multiple holes for
installation flexibility and the modular design allows blocks to snap together for the
desired number of poles. They accept optional snap-on covers for IP20 finger-safe
protection and feature a lockout/tagout provision to improve electrical safety.
