Mersen MPDBE6263 – Frequently Asked Questions

1) What does the Mersen MPDBE6263 end barrier actually do on a power distribution block?
MPDBE6263 is an open-style end barrier for the Mersen MPDB miniature power distribution blocks, not a block itself. It closes off the exposed end of an open-style PDB so the live terminal face is covered and the block keeps the spacing it needs for feeder and branch circuit use under UL508A and the NEC. If you need the block that does the splicing or the primary-to-secondary tap-off, order an MPDB62 or MPDB63 block; this part finishes it.
2) Which Mersen MPDB blocks does the MPDBE6263 barrier fit?
It belongs to the MPDB62 and MPDB63 miniature series. Those are the compact blocks in the Next Generation MPDB lineup, so the barrier is sized to that frame. It is not an accessory for the larger MPDB case sizes.
3) What short circuit rating do the Mersen MPDB mini blocks carry with this barrier?
10 kA standalone short circuit rating. If your panel's available fault current at that point exceeds 10 kA, the assembly has to be protected by an upstream device that brings it inside that figure, which is the usual UL508A series-rating exercise.
4) Will this Mersen barrier pass a UL508A panel inspection?
The MPDB mini end barrier is UL and CSA approved and offered under UL 1953, and the series is built to meet spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code. For a listed industrial control panel that is the paperwork an inspector looks for on the distribution block end treatment.
5) Is a 1000V end barrier rated for DC bus work as well as AC?
Both. The MPDB mini end barrier carries 1000 V AC and 1000 V DC UL ratings, with 50/60 Hz AC/DC operation, so it suits solar and DC bus panels as well as conventional AC feeder distribution.
6) How many Mersen MPDBE6263 barriers come in a pack?
They ship 25 each per pack, which is how Mersen packages this accessory. Worth knowing before you buy for a single panel build, since each open-style block typically needs barriers on the exposed end only.
7) Is the Mersen MPDB end barrier RoHS compliant for export panels?
Yes, MPDBE6263 is manufactured to RoHS requirements, so it is acceptable in panels built for restricted-substance jurisdictions.
