Power Distribution Blocks
Installation instructions
1 pole power distribution blocks can be linked together to form multi-pole
distribution blocks. The power distribution block/blocks mounted on 35 mm
DIN rail should be provided with DIN rail anchors to prevent damages on
the plastic insulation, see fig 1.
Fig 1.
Anchors are required on each
side of the block/blocks when
mounted on 35 mm DIN rail.
The power distribution blocks meet ingress protection IP 20 provided that
all terminal openings are used. The openings for the terminal screw meet IP
20 when they are tightened, also applicable to unused opening. IP 20 does
not apply when smaller conductor sizes are used, see table 1.

Short-circuit current rating (SCCR) according to UL 508A
Assembly short-circuit current rating (SCCR) is required for industrial control panels. Power distribution blocks may be one of the weakest links, an
unmarked power distribution block is assigned a short-circuit current rating
at 10 kA according to table SB4.1 in UL 508A.
surface, both for Branch Circuits and Feeder Circuits. The power distribution blocks are UL listed for higher SCCR in combination with Cooper
Bussmann fuses and Eaton Cutler-Hammer Series G MCCBs, see page 4,
table 3 and 4. Conductor sizing is based on 75°C according to NEC table
310.16 and UL 508A table 28.1.
Cooper Bussmann power distribution blocks are UL listed according to
UL 1953 and meet the UL 508A minimum spacing requirements, air and
