Overview

Introducing the Mersen MPDB68112, a robust open-style Power Distribution Block (PDB) engineered for demanding electrical applications. This large-format PDB, part of the MPDB68 series, offers exceptional performance with a 1000V voltage rating and a substantial 760A current capacity. Constructed from high-quality tin-plated copper, it ensures reliable conductivity and durability. The 2-pole configuration and box-to-box connection type facilitate straightforward and secure wiring. Designed for open-style mounting, the MPDB68112 is UL 1953 approved and meets stringent National Electrical Code® requirements when used in conjunction with UL508A for feeder and branch circuits. This specific model features 12 secondary openings, accommodating wire sizes from #4 AWG down to #14 AWG, with a primary input capacity for conductors up to #4 AWG. Mersen power distribution blocks are the next generation in safe and efficient power management, providing an easy method for splicing cables, splitting primary power into secondary circuits, and fulfilling requirements for fixed junction tap-off points. All Mersen PDBs are UL and CSA approved. The MPDB series is available in miniature, intermediate, and large size categories, with options for both aluminum and copper conductors, and can accommodate single or dual primary inputs with up to 30 secondary outputs. Specialty blocks are also available for up to 7 primary inputs. The MPDB68112 is manufactured in Germany (DE).

Special Features
Adder Poles: All sizes have optional adder poles for increased flexibility and ease-of-use. Adder poles can be stacked to form multi-pole units in the field without the use of tools. Adder poles allow for customization of primary and secondary wire combinations. End barriers are also available for sale, catalog numbers can be found in the catalog number selection tables for each size block. Wire Connectors: Standard aluminum and copper wire connectors are available. Aluminum connectors accept both AL or CU wire while copper connectors accept CU wire only. Connectors are all 1-piece tin-plated. Many part numbers are rated to accept DLO-type fine-strand wire, allowing users to connect flexible conductors. Insulators: Insulators are virtually unbreakable, made of glass-filled polycarbonate. “See-through,” hinged safety covers are optional and provide a greater degree of safety and shock resistance where required. Hinged covers can be installed without tools. Spacings: 1 inch through air and 2 inches over surface between uninsulated live parts of opposite polarity meets requirements for feeder and branch circuit applications of UL508A. Safety Covers: Polycarbonate safety covers provide dead-front protection. One cover is needed for each pole. Each cover has a test probe hole in the center for circuit checking. Covers are optional accessories and catalog numbers can be found in the catalog selection tables for each size block.
