Overview

The Mersen MPDB66200 is an open-style Power Distribution Block (PDB) designed for reliable power management in industrial applications. This model, part of the MPDB66/67 intermediate series, features a tin-plated copper construction for excellent conductivity and durability. It is rated for 1000V and a maximum current of 155A, with a single adder connection. The block offers one primary input and is designed to meet UL 1953 standards. Mersen power distribution blocks are engineered to provide a safe and efficient 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, meeting spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. The MPDB66200 specifically provides a stud-to-stud connection with 3/8-16 x 1-5/16 studs. This series is available in both aluminum and copper options, with miniature, intermediate, and large size categories to suit various installation needs.

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.
