Mersen MPDB66/67 Series Open-Style PDB End Barrier, 1000V

The Mersen Open-Style Power Distribution Block (PDB) End Barrier is part of the Next Generation MPDB series, engineered to provide a safe and easy method of splicing cables, splitting primary power into secondary circuits, and fulfilling requirements for fixed junction tap-off points. This intermediate-size (MPDB66/MPDB67) end barrier component is UL 1953 rated for 1000V AC/DC service at 50/60 Hz, with a standalone short circuit rating of 10 kA. As with all Mersen PDB components, it is built to meet spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code, and is RoHS compliant for use in modern industrial and commercial power distribution systems.

Key Features

  • Voltage Rating: UL rated 1000V AC and 1000V DC for demanding primary and secondary power distribution applications.
  • AC/DC Compatibility: Rated for AC/DC operation at 50/60 Hz, supporting a wide range of power distribution scenarios.
  • Short Circuit Rating: 10 kA standalone rating helps protect downstream circuits and equipment.
  • Open-Style End Barrier Design: Provides a secure termination point at the end of the block assembly for safe conductor management.
  • Intermediate Size Category: Part of the MPDB66 and MPDB67 intermediate series within Mersen's Next Generation PDB lineup.
  • RoHS Compliant: Manufactured to RoHS standards for environmentally responsible power distribution hardware.

Mersen MPDBE6667 – Frequently Asked Questions

1) What does the Mersen MPDBE6667 end barrier actually do on a power distribution block?
It is the insulating end cap for an open-style Mersen MPDB power distribution block, giving a closed termination point at the end of the block assembly so energized conductors and lugs are not left exposed at the open end. It carries no conductor itself, so it adds no circuits to the block, it closes it off.
2) Which Mersen MPDB block sizes does the MPDBE6667 end barrier fit?
It is the intermediate-size barrier, built for the MPDB66 and MPDB67 blocks in Mersen's Next Generation MPDB line. If your block is a different frame size in that series, the 66/67 barrier is the wrong part for it.
3) Is the Mersen MPDBE6667 barrier rated for 1000V DC solar and battery work, or AC only?
Both. UL rated voltage is 1000 V AC and 1000 V DC, at 50/60 Hz, so it is usable on DC distribution as well as conventional AC feeders.
4) Will a Mersen MPDB66/67 assembly with end barriers satisfy UL508A spacing in an industrial control panel?
Mersen PDB components, including the MPDB66/67 end barrier, are built to meet the spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code, and the barrier itself is UL 1953 rated. The barrier is part of how that spacing is achieved at the open end of the block, so panel builders specifying to UL508A should include it rather than leave the block end open.
5) What short circuit rating does the Mersen MPDB66/67 end barrier carry?
10 kA standalone. That figure governs what you can place it on without additional upstream limiting, so compare it against the available fault current at the point in the panel where the block sits.
6) Is the Mersen MPDBE6667 end barrier RoHS compliant for export builds?
Yes, it is manufactured to RoHS standards, which matters for OEM panel and switchgear assemblies shipping into markets that require RoHS documentation.
7) Where are Mersen open-style PDBs with end barriers typically used?
Typical work is splicing cables, splitting primary power into secondary circuits, and fixed junction tap-off points, in industrial panelboard and switchgear assemblies wired as feeder and branch circuits under UL508A and the NEC.
