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.
