Mersen MPDB Series Open-Style Power Distribution Block, UL 1953 1000V

The Mersen MPDB Series Open-Style Power Distribution Block (PDB) is the next-generation solution for splicing cables, splitting primary power into secondary circuits, and providing fixed junction tap-off points in industrial and commercial electrical systems. Rated 1000V AC/DC and listed to UL 1953 with 50/60 Hz frequency support, this PDB series is UL and CSA approved and engineered to meet the spacing requirements for feeder and branch circuits under UL508A and the National Electrical Code®. The MPDB platform is offered in miniature, intermediate, and large size categories, in both aluminum and copper, giving panel builders and OEMs a scalable power distribution option for demanding applications.

Key Features

  • Series Sizing: Available in three MPDB size categories – miniature (MPDB62 and MPDB63), intermediate (MPDB66 and MPDB67), and large (MPDB68 and MPDB69) – in both aluminum and copper.
  • Flexible Circuit Configuration: Supports single or dual conductor primary inputs with up to 30 secondary outputs; specialty blocks are available with up to 7 primary inputs.
  • Electrical Rating: Rated 1000V AC/DC (UL) at 50/60 Hz for reliable AC/DC power distribution.
  • Short Circuit Rating: 10 kA short circuit rating in standalone configuration.
  • Code-Compliant Spacing: Meets spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®.
  • RoHS Compliant: Manufactured to RoHS compliance standards for restricted substances.
  • Open-Style Construction: Simplifies field wiring access for splicing and tap-off connections in panel and enclosure builds.

Mersen MPDBC692W – Frequently Asked Questions

1) Can a Mersen MPDB power distribution block be used on a 1000V DC solar or battery circuit, or is it AC only?
Both. The MPDB Series carries a UL rating of 1000 V AC and 1000 V DC, with 50/60 Hz support on the AC side, so it works for DC distribution (solar, battery, drive DC bus) as well as conventional AC feeder and branch tap-offs.
2) Will a Mersen MPDB block satisfy an inspector on a UL508A industrial control panel?
It is built for that use. The MPDB Series is UL Listed to UL 1953 and CSA approved, and it meets the spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code. That is the combination a panel shop needs when the block is feeding tap-off points inside a listed control panel.
3) What short circuit current rating does the Mersen MPDB block contribute to a panel SCCR calculation?
10 kA standalone. If your panel SCCR is being set by the weakest component, the MPDB block holds 10 kA on its own; higher panel ratings depend on the upstream protective device combination you use.
4) How many secondary circuits can I tap off one Mersen MPDB distribution block?
The MPDB platform takes single or dual conductor primary inputs and supports up to 30 secondary outputs. Specialty blocks in the series go up to 7 primary inputs, which is the route to take if you are combining multiple sources rather than splitting one feeder.
5) I need a distribution block for a DC circuit - is the Square D 9080LBA or the Mersen MPDB the right choice?
The Mersen MPDB series is rated for AC/DC service, with a UL rating of 1000 V AC and 1000 V DC, so it is the block to specify when the tap-off point sits on a DC bus or on a mixed AC/DC panel. The Square D 9080LBA belongs to the Linergy 9080LB series in a 1 to 3 pole arrangement; choose it when the panel schedule names that series and pole count.
6) Should I specify the aluminum or the copper Mersen MPDB block?
The MPDB Series is offered in both across all three size classes. Copper blocks are the usual choice where copper conductors and lower-resistance connections are specified; aluminum-bodied blocks are the dual-rated workhorse for general panel splicing. The model MPDBC692W sits in the large (MPDB69) size class.
7) Is an open-style power distribution block OK for my application, or do I need a covered block?
Open-style means the terminations are accessible, which makes field splicing and tap-off wiring faster inside a panel or enclosure. It assumes the block lives behind a door or dead front, since there is no integral finger-safe shield. If the block will be reachable with the enclosure open and energized, specify a covered or finger-safe type instead.
8) Does the Mersen MPDB block meet RoHS for an export panel build?
Yes, the MPDB Series is manufactured to RoHS compliance for restricted substances, so it clears RoHS documentation requirements on equipment bills of material.
