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.
