Mersen MPDBC6667 – Frequently Asked Questions

1) Is the Mersen MPDBC6667 PDB cover rated for 1000V DC solar and battery circuits?
Yes. It carries a UL 1953 rating of 1000V on both AC and DC, with AC use rated at 50/60 Hz. That dual AC/DC rating is what lets it be used on DC distribution as well as conventional AC feeder and branch work.
2) Do I need the cover to pass a UL508A control panel inspection on a Mersen power distribution block?
The cover is the piece that makes an open-style block a code-compliant enclosure element. Mersen builds these covers to support UL and CSA approved PDB assemblies meeting UL508A spacing and National Electrical Code feeder and branch circuit spacing requirements. An uncovered open block does not give you that live-part protection, so panel builders order the cover with the block.
3) Does the MPDBC6667 include the power distribution block itself?
No. MPDBC6667 is the insulating cover only, sold one each. The aluminum or copper block from the Mersen MPDB series is ordered separately, and you pick the block first because the cover has to match its size.
4) What short circuit rating does the Mersen intermediate PDB carry?
10 kA standalone. That is the figure to check against the available fault current at the point in the panel where the block lands; if your calculated fault current exceeds it, you need series-rated upstream protection or a different block.
5) Can an open-style power distribution block be used for cable splicing and tap-off points?
That is exactly what the Mersen open-style PDB is built for: splicing cables, splitting primary power into secondary circuits, and serving as a fixed junction tap-off point in industrial and commercial panels. The cover goes over the top to keep the terminations enclosed.
6) Is the Mersen MPDBC6667 cover RoHS compliant for a spec that requires it?
Yes, the cover is RoHS compliant, which covers the material restriction line item on most institutional and government panel specs.
