FeaturesPDBs are often an assembly's lowest-rated component or features weak link and may limit the assembly SCCR to only 10kA, eliminate this weak link with these new, higher-rated PDBsEquipment with low SCCRs are limited to locations where only low-level short circuit current is availableBy replacing a low rated PDB with a new cooper bussmann high SCCR PDB, an assembly can achieve a higher SCCR for more installation flexibility4 AWG to 350 kcmil copper line, (12) 14 to 4 AWG copper load wire(1) box lug primary, (12) box lug secondary
