SKU CH-GMPM-GH7TX

Three-pole power distribution block rated 310 A at 600 V with single primary and secondary connections per pole accepting 6 AWG to 350 MCM wire

  • 310 A capacity handles heavy-duty power distribution
  • 600 V AC/DC rating supports industrial voltage requirements
  • Three-pole design enables three-phase connections
  • UL 1059 and CSA certified for safety compliance
  • Compact 5.37 × 2.8 × 2.12 in footprint saves panel space

Power Distribution Block 310 A 3-Pole

This Bussmann power distribution block handles up to 310 A across three poles at 600 V AC/DC. It suits installers who need a compact, open-design block for feeding multiple circuits from a single supply in industrial or heavy-duty automotive electrical panels.

Upgrade from Lower-Capacity Blocks

The jump is worth it when existing blocks are rated below 310 A or lack the 6 AWG to 350 MCM wire range on both primary and secondary connections. It replaces units that cannot accept large conductors or that do not carry the CSA Class 6228-01 and UL 1059 listings required for inspected installations.

Straightforward Panel Mounting

The block measures 2.8 in long, 2.12 in deep and 5.37 in wide, fitting standard enclosures with one primary and one secondary connection per pole. What usually goes wrong is using wire outside the 6 AWG to 350 MCM range or exceeding the 310 A rating, which voids the safety certifications and can cause overheating.

Questions about this item

What size enclosure opening is needed for the 5.37 in wide by 2.12 in deep block?

The block measures 5.37 in wide, 2.12 in deep and 2.8 in long; allow clearance for those outer dimensions plus wiring bend radius when planning the cut-out or DIN rail spacing.

Which torque value should be used when tightening the single 6 AWG to 350 MCM primary lug per pole?

Torque is not printed on the block; follow the lug manufacturer’s specification for the conductor size actually installed and verify each of the three poles individually.

How often should the three-pole 310 A block be inspected for discoloration or loose connections?

Inspect at least annually or after any overload event; look for heat discoloration on the open-design body and re-torque each primary and secondary lug if movement is found.
