Selecting SCCR power distribution blocks and
terminal blocks
Short-circuit current rated power distribution blocks
Bussmann series power distribution blocks have three distinct
styles to match different application needs. There are the PDBFS_
and PDB_ high short-circuit current rated power distribution blocks
and the 16_ power terminal blocks. The differences are whether the
power distribution blocks are enclosed or not, and whether they are
UL 1953 Listed power distribution blocks or UL 1059 Recognized
power terminal blocks, which have different minimum spacing
requirements. The table on this page will assist you in selecting
which block is right for your application.
Why these are important
Per the NEC and OSHA, equipment cannot be installed in an
electrical system at a location where the available fault (short-circuit)
current is greater than the equipment's SCCR.
Further, equipment SCCRs are required in the 2014 NEC and for UL
508A Listed control panels. Marking the equipment SCCR on control
panels (NEC 409.110), industrial machinery electrical panels (NEC
670.3(A)), and HVAC equipment (NEC 440.4(B)) is required by the
NEC.
Catalog
symbol
Power distribution and terminal blocks not marked with a component
SCCR are typically one of the weakest links in a control panel's
equipment SCCR and may limit the equipment SCCR to no more
than 10 kA. The PDBFS_ and PDB_ products have the increased
spacing required for use in feeder circuits of equipment listed to
UL 508A (UL 1059 terminal blocks must be evaluated for proper
spacings). Also, for building wiring systems, the PDBFS_ and
PDB_ power distribution blocks can be used to meet the 2014 NEC
requirements in section 376.56(B) for power distribution blocks in
wireways.
Selection table
The table below provides an overview of the three Bussmann
series power distribution and terminal blocks mentioned above. For
details on the PDB_ blocks, see data sheet number 10537. For the
16_ blocks, see data sheet numbers 10533 (UL Recognized power
distribution blocks), 10534 (splicer blocks) and 10535 (stud blocks).

PDBFS UL Listed finger-safe, high SCCR power
distribution blocks
These single pole, small footprint, high
Short-Circuit Current Rating (SCCR) power
distribution blocks provide IP20* fingersafe protection in a modular design that
permits dovetailing together the required
number of poles and still meet the UL
1953 minimum 1" and 2" spacing required
per UL 508A for feeder circuit applications
and per NEC for field installations.
Catalog number example — PDBFS204 is a 1-pole block
Where:
2011/65/EU
With SCCRs up to 200 kA, these blocks
help achieve compliance with NEC and
OSHA requirements by resolving a
common SCCR "weak link" in industrial
control panels.
To increase application flexibility, these
blocks feature dual-wire rated ports that
accept copper or aluminum conductors
while retaining a UL Listed status.
With panel or 35mm DIN-Rail** mounting these blocks are suitable
for installation in wireways and industrial control panel feeder and
branch circuits.
••
The catalog symbol "PDBFS" defines the block as a finger-safe
design
••
The catalog number ending "204" in this example defines this
block's lineside and loadside characteristics covering the amp
rating, number of ports and wire sizes, etc.
••
See the catalog number table for details on the available
lineside/loadside characteristics.
Features
••
IP20 finger-safe under specified conditions increases safety by
isolating energized connections
••
Wire-ready captive termination screws cannot be misplaced and
are shipped "backed out" to save time on conductor installation
••
Sliding DIN-Rail latch provides easy block mounting
••
For multiple pole applications, all single-pole units can be gang
mounted by using the interlocking dovetail pins that are preinstalled on the side of the blocks
••
Elongated panel-mounting holes provide greater flexibility and
installation ease when matching up with drilled panel holes
* See table on page 9-5.
** PDFFS504 panel mount only.
Dual wire port application
Ratings
••
Rated for dual wire port application to increase the possible
number of lineside and loadside connections. E.g., PDBFS220 can
accept two wires into the lineside port (4 - 14 Cu, 4 - 8 Al) and two
wires per port (eight connections total) on the loadside lug (8 - 14
Cu, 8 Al).
••
Dual wire applications are only viable when using two wires of the
same size, stranding, and insulating and conductor material.

that defines the desired lineside/loadside port and conductor
characteristics
••
Order one block per pole for the application
••
Multiple single-pole blocks can be ganged together via the
dovetailing feature to form multi-pole configurations
To gang two or more blocks for DIN-Rail or panel mounting, place
them side-by-side and slide the dovetail pin of one block into the
reciprocal slot on the other until fully seated and both blocks are
coplanar.
Note: Dissimilar PDBFS blocks can be ganged. E.g., a PDBFS204
can be ganged with a PDBFS220. Ganging with a PDBFS504 (nonDIN Rail mount version) will prevent DIN-Rail mounting.

accept two wires into the lineside port (4 - 14 Cu, 4 - 8 Al) and two
wires per port (eight connections per pole total) on the loadside
lug (8 - 14 Cu, 8 Al).
To increase application flexibility, these blocks feature dual-wire rated
ports that accept copper or aluminum conductors while retaining a
UL Listed status.

How to order
From the catalog number table, select the catalog number
that defines the desired lineside/loadside port and conductor
characteristics.
Add to the catalog number the suffix that defines the desired pole
configuration. Note, you must select from the available number of
poles for each catalog number. These appear in the second column
of the catalog number tables.
Catalog number example — PDB323-3 is a 3-pole PDB323
Where:
••
The prefix “PDB323” defines the block’s lineside characteristics
(i.e., one conductor port per pole that accepts 350kcmil - 6 Cu/Al
conductors) and the loadside characteristics (i.e., six (6) conductor
ports per pole that each accepts 4 - 14 Cu or 4 - 12 Al conductors)
••
The suffix “3” in this example defines this as a three-pole block
••
See the catalog number table for details on the available lineside/
loadside characteristics
From the table below, order the cover catalog number that matches
the block catalog number. Order the quantity indicated in the “order
quantity” column. E.g., the 3-pole block PDB204-3 requires ordering
three CPB162-1 covers (one cover for each pole).

Power distribution and terminal blocks — 9
Port-to-stud and stud-to-stud power
terminal blocks are available with current
ratings up to 760 A. These blocks provide
a convenient stud connection means for
lug/ring wire terminals.
Factory configured from 1- to 3-poles
(catalog number dependent) with
optional covers to enhance safety (order
covers separately), these blocks are UL
Recognized to UL 1059 and rated for use
in UL 508A industrial control panels.
Dual wire port application
••
Rated for dual wire port application to increase the possible number
of lineside and loadside connections. E.g., 16280-1 can accept two
wires into the lineside port (#4 - #8 Cu/Al, #10 - #14 Cu).
••
Dual wire applications are only viable when using two wires of the
same size, stranding, and insulating and conductor material in the
same port
Ferrule terminal application
••
Bussmann series stud blocks are rated for use with UL Listed
ferrules (see catalog number table for details). Ferrule ratings apply
to copper wire only.
••
Ferrule applications allow for the use of a broader range of
conductor stranding and simulate a more efficient, solid wire
connection with the terminal port
••
Always use UL Listed ferrules in accordance with the
manufacturer’s specifications and instructions
Ratings
••
Volts 600 V
••
Amps 150 up to 760 A
••
SCCR up to 200 kA*
(see table for SCCR by catalog number)
* Maximum SCCR contingent upon the application of an upstream current-limiting
overcurrent protective device. See table for fusing requirements.
Conductors†
••
Stranded 75°C copper and aluminum
••
Higher temperature rated conductors permitted with appropriate
derating
As specified in the catalog number table.

How to order
From the catalog number tables, select the catalog number
that defines the desired lineside/loadside port and conductor
characteristics.
Add to the catalog number the suffix that defines the desired pole
configuration. Note, you must select from the available number of
poles for each catalog number. These appear in the second column
of the catalog number tables.
Catalog number example — 16280-3 is a 3-pole 16280
Where:
••
The prefix “16280” defines the block’s lineside characteristics
(i.e., one conductor port per pole that accepts 2/0 - 14 Cu/Al
conductors) and the loadside characteristics (i.e., 1/4-20 x 3/4”
stud)
••
The suffix “3” in this example defines this as a three-pole block
••
See the catalog number tables for details on the available lineside/
loadside characteristics
Optional covers
Electrical safety can be enhanced by installing optional covers. From
the table below, order the cover catalog number that matches the
block catalog number.

Power distribution and terminal blocks — 9
160, 162, 163 and 165 UL Recognized power
splicer blocks
Splicer blocks allow for increasing
or decreasing wire size within a
circuit to accommodate different
connections from the power
source to the branch load.
These blocks are factory
configured from 1- to 4-poles
(catalog number dependent) for
wire sizes up to 500kcmil and
amp ratings up to 760 A. Optional
covers are available to enhance
safety (order covers separately).
These blocks are UL Recognized to UL 1059 and rated for use in UL
508A industrial control panels.
Ratings
••
Volts 600 V
••
Amps 115 to 760 A
••
SCCR up to 200 kA* (see table for SCCR by catalog number)
Dual wire port application
••
Rated for dual wire port application to increase the possible
number of lineside and loadside connections. E.g., 16303-1 can
accept two wires into the lineside port (1/0 - #6 Cu/Al) and two
wires per port (2 connections per pole total) on the loadside lug
(1/0 - #6 Cu/Al).
••
Dual wire applications are only viable when using two wires of the
same size, stranding, and insulating and conductor material in the
same port.
Ferrule terminal application
••
Bussmann series splicer blocks are rated for use with UL Listed
ferrules (see catalog number table for details). Ferrule ratings apply
to copper wire only.
••
Ferrule applications allow for the use of a broader range of
conductor stranding and simulate a more efficient, solid wire
connection with the PDB terminal port
••
Always use UL Listed ferrules in accordance with the
manufacturer’s specifications and instructions
