Two-pole 310 A distribution block

The Mersen MPDB67002 is a two-pole power distribution block rated for 310 A at 1 000 V AC/DC. It accepts copper conductors from 6 AWG up to 350 kcmil on both line and load sides, with one connection per pole. The open, surface-mount design suits industrial panels and generator hook-ups.

Thermal and power profile

Rated current of 310 A assumes properly torqued copper lugs within the 6 AWG to 350 kcmil range. The open construction allows free air flow around conductors, limiting temperature rise under continuous load. No forced cooling or active components are present, so acoustic output is negligible in normal operation.

Integration requirements

The block measures 3.08 in long, 3.57 in wide and 3.25 in deep, requiring a flat mounting surface with adequate clearance for the largest cable bend radius. Two poles free the installer from paralleling single-pole units, reducing hardware count and potential hot spots. Verify panel space and wire routing before installation.

Questions about this item

How do I surface-mount the MPDB67002 and what torque step is often missed?

Mount the block on a flat panel using the base holes, then torque each 6 AWG–350 kcmil line and load lug to the lug manufacturer’s spec; the step most often missed is re-torquing after the first heat cycle.

What maintenance will the MPDB67002 need over time?

Inspect the two-pole copper bars annually for discoloration, verify lug torque on the 6 AWG–350 kcmil conductors, and clean any oxide buildup with a non-abrasive pad before re-torquing.

At what current does the 310 A rating become the limiting factor during sustained loads?

The 310 A copper-conductor rating is the first limit reached under continuous operation at 1 000 V AC/DC; sustained loads above 310 A will exceed the block’s rated capacity.
