760 A Three-Pole Distribution Block

The Mersen MPDB69093 is an open-style power distribution block rated for 760 A at 1,000 V. It provides three poles with two line and two load connections per pole, accepting copper or aluminium conductors from 4 AWG up to 500 kcmil. The unit mounts on a flat surface and measures 3.55 in overall depth.

Suited for High-Current Panel Builds

Electrical contractors and panel shops wiring heavy-duty feeder circuits will find the 760 A copper rating and 1,000 V insulation suitable for main distribution. Installers needing a compact DIN-rail mount, an enclosed housing or a higher pole count should consider alternative designs not covered by this model.

Verify Conductor Size and Mounting Space

Confirm that your incoming and outgoing cables fall within the 4 AWG to 500 kcmil range and that the lugs or compression fittings you plan to use match the studless connection style. Ensure the mounting surface can accommodate the 3.55 in depth and provides adequate clearance for cable bending radius.

Questions about this item

What conductor sizes does the Mersen MPDB69093 accept for the line and load connections?

The block accepts copper conductors from 4 AWG up to 500 kcmil on both the line and load sides, with two connections per pole.

Will the MPDB69093 carry the same 760 A rating if I use aluminium conductors instead of copper?

The 760 A maximum current rating applies only to copper conductors; aluminium conductors are supported but have a lower ampacity that must be calculated separately.

How can I confirm the MPDB69093 is operating within its 1000 V and 760 A limits after installation?

Measure the voltage across each pole to ensure it stays at or below 1000 V and use a clamp meter on the conductors to verify current does not exceed 760 A per pole.
