  • Accepts 2 AWG to 600 kcmil copper conductors

MPDB69331 Power Distribution Block 1260 A

The MPDB69331 is a single-pole open power distribution block rated for 1260 A at 1000 V AC/DC. It accepts aluminum conductors and provides three line and three load connections per pole for copper wire sizes ranging from 2 AWG to 600 kcmil. Surface-mount installation suits industrial panel builders and OEM integrators.

Suited for high-current copper feeds in heavy-duty

This block serves installers who need to split or combine large copper conductors in a compact footprint. It is not intended for multi-pole distribution, for line-side conductors smaller than 2 AWG, or for applications requiring enclosed or finger-safe housings. Builders needing more than one pole or a different mounting method should look elsewhere.

Surface-mount block measuring 5.7 in long 5.32

The unit mounts directly to a panel or backplate, freeing DIN rail space for other components. Its open design allows visual inspection of terminations and easy access for torque verification. Ensure the enclosure provides adequate clearance for the stated wire bending radius and the 1000 V insulation requirements.

Questions about this item

What minimum and maximum copper wire sizes does the MPDB69331 accept on its three line and three load connections per pole?

The block accepts copper conductors from 2 AWG up to 600 kcmil on each of the three line and three load connections per pole.

Can the 1,260 A copper rating of the MPDB69331 be used with existing aluminium conductors in a 1,000 V AC/DC system?

The 1,260 A rating applies only to copper conductors; aluminium conductors are not rated for that current on this block.

After surface-mounting the MPDB69331, how can I verify the block is operating within its 1,000 V AC/DC and 1,260 A limits?

Measure voltage across each pole with a calibrated meter to confirm it stays at or below 1,000 V AC/DC, and use a clamp meter on each conductor to ensure current does not exceed 1,260 A.
