Power Distribution Block
Maximize Short-Circuit
Current Rating While
Improving Safety
UL Listed, IP-20 Enclosed
Power Distribution Block
Offer High SCCR
New 2005 NEC
®
and UL508A 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 UL1953 for minimum spacing requirements of at least 1˝
through air and 2˝ over surface as required for UL508A 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. IP-20 finger-safe under specific conditions.
• Easy Panel Mounting
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.
• Meet Wireway Requirements
Series PDBFS can be used to meet the new 2005 NEC
®
376.56(B)
requirement.

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.
