New Cooper Bussmann® PDB Series Power Distribution Blocks with High SCCR Increase Assembly Short-Circuit Current Ratings
ST. LOUIS, May 4, 2006 - With high SCCRs up to 200kA and listed to UL1953, the new Cooper Bussmann PDB Series of power distribution blocks can replace low-rated power distribution blocks to achieve higher assembly short-circuit current ratings.
The 2005 NEC® now requires industrial control panels, some HVAC equipment and other assemblies to be marked with their assembly short-circuit current rating. Power distribution blocks with a default SCCR of only 10kA are often the cause of a low assembly SCCR for industrial control panels. Cooper Bussmann’s new PDB Series of power distribution blocks provides a solution for these daunting applications.
Equipment with low SCCRs are limited to locations where only low-level short-circuit current is available. By replacing a low-rated power distribution block with a new Cooper Bussmann high SCCR PDB Series power distribution block, an assembly can achieve a higher SCCR for more installation flexibility.
These new power distribution blocks can be used to meet the new 2005 NEC® requirement in section 376.56(B) for wireways. They also can be used in UL508A panels for both feeder and branch circuit applications.
