Mechanical • Panel mount • Flammability, UL 94V0 • Tin-plated Al connectors suitable for Cu conductors
Electrical • 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 and2” over surface • Ratings available with circuit breakers
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. (Tables on Catalog page 296)

Features

  • 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
