UL Listed, Finger-Safe
Enclosed Power Distribution
Blocks Offer High SCCR
New 2008 NEC®and UL 508A SCCR marking requirements state
that the following equipment must be marked with an assembly
SCCR:
• Industrial Control Panels [409.110]
• Industrial Machinery Electrical Panels [670.3(A)]
• Certain HVAC Equipment [440.4(B)]
This SCCR is based on the lowest-rated component, or weakest
link, in the assembly. Unmarked power distribution blocks will default
to a rating of 10kA. The new Cooper Bussmann®enclosed Series
PDBFS offers both high SCCR and enhanced shock protection.
• UL Listing Meets Requirements Eliminating
Investigation and Procedures
Listed to UL 1953 for minimum spacing requirements of at least 1˝
through air and 2˝ over surface as required for UL 508A industrial
control panel feeder applications. See back page.
• High SCCR
Up to 200kA rating enables the power distribution block to be one
of the highest rated devices in the panel. This helps achieve a high
assembly SCCR.
• Enclosed for Enhanced Electrical Safety
Safer work conditions. Finger-safe and IP20 under specific
conditions.
• Modular, Space Saving Design
Gangable for flexible multi-pole installations, plus small footprint
for tight spacing.
• Simple and Fast Installation
DIN rail mount or panel mount, (See datasheet 1049). Captive
terminal screws are backed out at the factory.
• Meets Wireway Requirements
Series PDBFS can be used to meet the new 2008 NEC®376.56(B)
requirement, which requires listed PDBs and no exposed live parts
with or without wireway cover installed.

UL Listed 1953 vs. UL Recognized 1059
Listed products require simply checking to ensure that the
product is used in accordance with its listing and labeling.
However, for recognized products, such as power terminal
blocks, the “Conditions of Acceptability” must be
investigated to ensure the product is suitable for the
specific application, and then the procedure description
must be documented in the manufacturer’s procedure for
the assembly.
