Cooper Bussmann PDB321-2 Power Distribution Block

Cooper Bussmann PDB321-2 is a UL 1953-listed two-pole power distribution block designed for distributing power within electrical panels while meeting high-SCCR safety requirements. This model is rated for up to 600 V (AC and DC) and 175 A, with line terminals sized for 2/0–8 AWG copper and load terminals accommodating 4–12 AWG copper conductors, providing a compact, panel‑level distribution point for multiple outputs. The block features IP-20 finger-safe protection and tin-plated aluminum connectors, along with a 200 kA SCCR rating, making it suitable for building distribution networks in control panels where high short‑circuit withstand is required. Optional covers are available for PDB321-series blocks (one cover per block, not per pole) to seal unused positions.
