Overview

The Mersen MPDB69160 is an open-style Power Distribution Block (PDB) designed for robust power management in industrial applications. This unit, part of Mersen's large series (MPDB68 and MPDB69), features a tin-plated aluminum construction, offering reliable conductivity and durability. It is rated for 1000V and a primary current of 270A, with a 350A adder for increased capacity. The block provides 12 secondary openings, accommodating wire sizes from 2/0 to #14 AWG for primary inputs and #4 to #14 AWG for secondary connections between boxes. Mersen power distribution blocks are engineered for safe and efficient cable splicing, splitting primary power into multiple secondary circuits, and serving as fixed junction tap-off points. All Mersen PDBs, including the MPDB69160, are UL and CSA approved and meet spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. This model offers dual conductor primary inputs and is suitable for applications requiring reliable power distribution and circuit segmentation. The MPDB series is available in miniature, intermediate, and large sizes, with options for both aluminum and copper conductors.

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.
