Mersen MPDB67013 Open-Style Power Distribution Block, 1000V 250A/310A 3-Pole Tin-Plated Aluminum

The Mersen MPDB67013 open-style power distribution block delivers reliable, code-compliant power distribution for demanding electrical systems. Built to UL 1953 standards, this 3-pole block is rated 1000V AC/DC with a dual amperage rating of 250A for aluminum conductors and 310A for copper conductors. Tin-plated aluminum connectors and a glass-filled polycarbonate body combine corrosion resistance with strong dielectric insulation for long-term, high-voltage performance.

Key Features

  • Dual Amperage Rating: 250A on aluminum conductors and 310A on copper conductors gives installers flexibility across conductor types.
  • 1000V AC/DC Rating: High-voltage capability supports demanding industrial and commercial power distribution applications.
  • Tin-Plated Aluminum Connectors: Corrosion-resistant plating on box-to-box connectors extends service life and maintains reliable connections.
  • Glass-Filled Polycarbonate Body: Provides excellent dielectric strength and mechanical durability for long-term reliability.
  • 100 kA Short Circuit Rating: High fault-current capability with appropriate fusing (Class CC, G, J, L, RK1, RK5, T) delivers robust system protection.
  • Versatile Wire Range: Primary wire range of 350-#6 and secondary wire range of 2/0-#14 accommodate diverse conductor sizing.
  • 3-Pole, Direct Screw Mount: Box-to-box connector configuration with direct screw mounting simplifies professional installation.

Mersen MPDB67593 – Frequently Asked Questions

1) Can I use the Mersen MPDB67013 on both aluminum and copper conductors?
Both. The block is rated 250 A with aluminum conductors and 310 A with copper, and the connectors themselves are tin-plated aluminum, which is the standard dual-rated arrangement. Size your ampacity to whichever conductor material you are actually landing, not to the higher number.
2) What is the real short circuit current rating of the MPDB67 block in my panel?
Standalone it is 10 kA. It reaches 100 kA only when protected by an appropriate upstream fuse: 100 kA with a 30 A Class CC fuse, and 100 kA with a 60 A Class G fuse. If your SCCR calculation needs more than 10 kA, the fuse class and size ahead of the block is what gets you there.
3) Is this power distribution block rated for 1000V DC solar and battery circuits?
Yes, it is rated 1000 V on both AC and DC per UL, and AC use covers 50/60 Hz. That DC rating is what makes it usable in PV and energy storage collection wiring as well as conventional 480 V or 600 V AC distribution.
4) Do I need a DIN rail or an enclosure kit to mount the Mersen MPDB67?
No rail is involved. It is a direct screw mount block, so it fastens straight to the panel back pan or subplate. It is also open style, meaning the terminals are exposed, so it must go inside an enclosure or be fitted with covers to meet finger-safe requirements in an accessible location.
5) How much panel space does the Mersen MPDB67 block need?
Plan for 5.28 inches wide by 3.08 inches long by 3.25 inches high, and about 1.6 lb of weight on the subplate. Add clearance beyond that for the bend radius of a 350 kcmil conductor coming into the primary lug.
6) What is the difference between the two Mersen MPDB67 blocks, 250A/310A and 175A?
They are the same 3-pole open-style family in two current sizes. MPDB67013 is the 250 A aluminum / 310 A copper block with the 350-#6 primary range. MPDB67593 is the 175 A version. Pick by the feeder ampacity and the conductor size you have to land, not by the branch count.
7) Is the Mersen MPDB67 UL listed and RoHS compliant for a spec job?
It is built to UL 1953, the standard for power distribution blocks, and it is RoHS compliant. Those are the two line items most submittal packages ask for on a block like this.
8) Can I swap a Square D 9080LB block in place of a Mersen MPDB67 one-for-one?
Treat them as different parts rather than drop-in equals. The Mersen MPDB67 series has its own footprint at 5.28 in wide, 3.25 in high and 3.08 in long with direct screw mounting, and it is rated 1000 V on both AC and DC with a 10 kA standalone short circuit rating. The Square D 9080LBA belongs to the Linergy 9080LB series and covers 1 to 3 poles, so confirm the pole count, wire range and mounting centers against the enclosure before substituting either way.
9) Is the Mersen MPDB67 block suitable for a wet or corrosive plant environment?
The connectors are tin-plated aluminum for corrosion resistance and the body is glass-filled polycarbonate, which gives good dielectric strength and mechanical toughness. It is still an open-style block, so environmental protection comes from the enclosure it is installed in, not the block.
