PDB series of Power Distribution Blocks

• High short-circuit current ratings up to 200kA. These PDBs do not have to be the weak link in achieving high SCCR for an industrial control panel
• Listed to UL 1953 which has minimum spacing requirements at 600V of at least 1” through air and 2” over surface required for feeder in UL 508A Industrial Control Panels
• For 2D CAD drawings contact Bolfmax.

• UL Listed 1953, Guide QPQS, File E256146

• 600Vac/dc (UL 1953)
• Short-circuit current ratings up to 200kA, see table
• 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
• Ratings available with circuit breakers

• Panel mount
• Flammability, UL 94V0
• Tin-plated Al connectors suitable for Cu conductors

Optional covers
Covers are ordered for each individual pole, i.e., three 1-pole covers for 3-pole block, see table A.
Except PDB321 blocks have one cover for 1, 2 or 3 pole versions, see table B.
