Series HPB Power Distribution Blocks
Agency/Standards
• UL Listed 1953, Guide QPQS, File E333541
Electrical
• 600Vac/dc (UL 1953)
• Short-Circuit Current Ratings up to 200kA, see table
• 75ºC rated connectors, ampacities up to 310A
• Wire range 14 AWG to 350 kcmil Cu
• Spacing between uninsulated opposite polarities or ground
meets UL 1953 which requires at least 1” through air and
2” over surface for 301 to 600Vac/dc
Feature/Benefits
• High Short-Circuit Current Ratings up to 200kA. These
PDBs do not have to be a weak link in achieving high
SCCR for an industrial control panel
• Suitable for installation in wireways (with optional covers)
and industrial control panel feeder and branch circuits
• Listed to UL 1953 which has minimum spacing
requirements at 600Vac/dc of at least 1” through air and 2”
Mechanical
• Panel mount
• Flammability, UL 94V0
• Tin-plated Al connectors suitable for Cu conductors
