Mersen MPDB67013 – Frequently Asked Questions

1) What wire sizes can I land on the Mersen MPDB67013 power distribution block?
The line side takes one conductor per pole, 350 kcmil down to #6, through a 0.75 inch box opening. Each pole then feeds out through two secondary openings sized 2/0 down to #14, with a 0.44 inch hole diameter. So one 3-pole feeder in, up to six loads out.
2) Is the MPDB67013 block rated 250A or 310A?
Both, depending on what you land in it. The MPDB67013 carries 250A when the conductors are aluminum and 310A when they are copper. Size your feeder to whichever number matches the wire you are actually pulling, not the higher figure on the label.
3) Can this Mersen distribution block be used on a 1000V DC solar or battery system?
Yes. The MPDB67013 is rated 1000V on both AC and DC under UL, and the AC side covers 50/60 Hz. That DC rating is what makes it usable in PV combiner and energy storage work, where a block rated only for AC would not qualify.
4) What short circuit current rating do I use for my panel label, 10 kA or 100 kA?
Standalone, the MPDB67013 is 10 kA. It reaches 100 kA only when protected by a specific upstream fuse: Class CC at 30A, Class G at 60A, Class RK5 at 100A, Class RK1 at 200A, and Class J, L or T at 400A. If your overcurrent device is a circuit breaker or a fuse larger than those limits, the 10 kA figure is the one that goes on the equipment SCCR label.
5) What torque do I tighten the lugs to on the MPDB67013?
Primary connections across the full 350 kcmil to #6 range go to 275 in-lb. On the secondary side, 2/0 through #6 takes 120 in-lb and #8 through #14 takes 50 in-lb. The screws are hex: 11/16-16 x .88 on the primary, 7/16-20 x .55 on the secondary, so bring the right hex key sizes to the job.
6) Can I land aluminum conductors in the Mersen MPDB67013, or is it copper only?
Aluminum is fine. The connectors are tin-plated aluminum box lugs, AL/CU capable, and the block carries a separate 250A rating for aluminum conductors alongside 310A for copper. The tin plating is what keeps the aluminum-to-aluminum joint from corroding over time.
7) Will the Mersen MPDB67013 fit in my enclosure?
The block measures 3.25 x 3.08 x 5.28 inches and weighs 1.6 lb. It is an open-style block with no cover, so plan clearance for bending radius on 350 kcmil conductors and for the live parts, which are exposed unless you add a barrier or mount inside a locked enclosure.
8) How does this block mount, and do I need a DIN rail?
No rail. The MPDB67013 is direct screw mount, so it fastens straight to a subpanel or backplate. If your build standardizes on DIN rail, this is not the block for it.
9) If I swap a Square D Linergy 9080LB out for the Mersen MPDB67013, what changes at install?
Plan for different panel real estate and different torque. The Mersen MPDB67013 measures 5.28 in wide by 3.25 in high by 3.08 in long, weighs 1.6 lb, and is a direct screw mount block. Its lugs are box type on both primary and secondary, with an 11/16-16 x .88 hex screw on the primary and 7/16-20 x .55 on the secondary, torqued to 275 on the 350-#6 primary and 120 on 2/0-#6 secondary conductors, 50 on #8-#14. The Square D Linergy 9080LB is a 3-pole block, so verify its footprint and mounting hole pattern against your existing backplate before reusing the holes.
10) Is the body material good enough for a hot industrial or data center room?
The MPDB67013 uses a glass-filled polycarbonate body, which is the standard choice for high-dielectric, mechanically stressed distribution blocks, and it is RoHS compliant for facilities with restricted-substance procurement rules.
