620 A 1000 V Power Distribution Block

The Mersen MPDB69123 is a three-pole open power distribution block rated for 620 A at 1000 V. It accepts copper or aluminium conductors from 6 AWG up to 350 kcmil on both line and load sides with two connections per pole. Surface mounting suits panel builders and industrial electricians wiring main distribution panels or generator hook-ups.

Verify conductor range and mounting

Confirm that your incoming and outgoing cables fall within the 6 AWG to 350 kcmil window for copper conductors. The block provides two line and two load connections per pole with no stud hardware supplied, so lugs or compression terminals must be sourced separately. Ensure the 3.55 in overall depth fits the available panel space and that the 1000 V rating matches your system voltage.

Integrates into three-phase distribution

The block distributes three phases in a compact open frame, freeing DIN rail space for breakers or contactors downstream. It requires a flat mounting surface and appropriate lugs for the chosen conductor size. No auxiliary contacts or monitoring features are included, so additional metering or protection devices must be added externally if required.

Questions about this item

Does the Mersen MPDB69123 include mounting hardware or terminal lugs, or must those be purchased separately?

The block is supplied as an open, surface-mount unit; mounting fasteners and compression lugs for the 6 AWG to 350 kcmil copper conductors are not included and must be sourced separately.

How do I decide whether the 620 A, 1,000 V three-pole block suits my application versus a lower-rated version?

Choose this model when the circuit carries up to 620 A per pole at 1,000 V and you need two line and two load connections per pole for copper conductors between 6 AWG and 350 kcmil.

What does the 620 A rating mean when the block is installed in a panel with 350 kcmil copper cables?

With 350 kcmil copper conductors the block can continuously carry 620 A per pole at up to 1,000 V, provided the installation meets the required torque and spacing for the open surface-mount design.
