Mersen MPDB67512 two-pole distribution block

The Mersen MPDB67512 is a two-pole power distribution block rated for 350 A and 1000 V AC/DC. It accepts line conductors from 14 AWG up to 2/0 AWG and provides six load connections per pole for wires from 14 AWG to 2 AWG. The open, surface-mount design suits industrial panels and generator hook-ups where multiple branch circuits feed from a single supply.

Continuous 350 A rating with copper conductors

The block carries its full 350 A rating on copper conductors without derating for short bursts. Aluminium conductors are also supported, though ampacity follows standard aluminium tables. Six load terminals per pole keep voltage drop predictable across parallel feeds, and the 1000 V insulation withstands sustained industrial line voltages.

Two-pole 350 A at 1000 V decides fit

The combination of two poles, 350 A copper rating and 1000 V AC/DC withstand is the single specification that determines whether this block matches the panel design. Installers needing a different pole count, higher current or lower voltage class must select an alternative part.

Questions about this item

Will the 350 A block run hot or draw extra power when loaded continuously?

The block is a passive copper conductor rated for 350 A at 1 000 V AC/DC, so it generates no heat of its own and consumes no power beyond the normal I²R losses of the cables you connect.

What wire sizes and tools must I have on hand to terminate the 2/0 AWG line and 2 AWG load connections?

You need copper conductors from 14 AWG up to 2/0 AWG for the two line terminals per pole and 14 AWG up to 2 AWG for the six load terminals per pole, plus a crimper or lug tool sized for those ranges.

Can the 3.08 in by 3.57 in footprint sit next to my existing 1 000 V surface-mount busbars without clearance issues?

The block measures 3.08 in long, 3.57 in wide and 3.25 in deep with surface-mount tabs, so you can check those dimensions against the spacing of your current busbar layout.
