Selection Table for SCCR Power Distribution Blocks and
Power Ter minal Blocks
Shor t-Circuit Current Rated Power Distribution
Blocks
Cooper Bussmann of fers three distinctly dif ferent styles of
short-circuit cur rent rated power distribution blocks (PDBs)
and power terminal blocks (PTBs) to ma tch different
application needs. The dif ferences are whether the power
distribution blocks are enclosed or not, and whether they are
UL1953 Listed PDBs or UL1059 Recognized PTBs, which
have different minimum spacing requirements. The table on
this page can assist in the selection of the right series for
your application requirements.
Why these are impor tant?
Assembly short-circuit cur rent ratings (SCCRs) are now
required in the 2008 NEC
®
and UL 508A Listed Industrial
Control Panels. Mar king the SCCR on Industrial Control
Panels (NEC
®
409.110), Industrial Machiner y Electrical
Panels (NEC
®
607.3(A)), and HVAC equipment (NEC®
440.4(B)) is now required by the National Electrical Code.
PDBs or PTBs not marked with a SCCR, typically are the
weakest link and may limit an assembly to no more than 10kA
SCCR. The PDBFS and PDB Series have increased spacing
required where used in feeder circuits in equipment listed to
UL508A (UL1059 PTBs must be evaluated for proper spac-
ings). Also, for building wiring systems, the PDBFS Series
and PDB Series power distribution blocks can be used to
meet the new 2008 NEC
®
requirements in section 376.56(B)
for PDBs in wireways.

Feature/Benefits
• Enclosed, safer
installation; IP20
finger-safe under specific
conditions
• High short-circuit current
ratings up to 200kA:
PDBs do not have to be
the weak link in achieving
high SCCR for an
industrial control panel
• Small footprint saves
panel space
• Listed to UL 1953 which has minimum spacing
requirements at 600V of at least 1” through air and 2” over
surface required for feeders in UL 508A Industrial Control
Panels
