Overview

The Mersen MPDB66201 is an open-style Power Distribution Block (PDB) engineered for reliable power management in industrial applications. Constructed from tin-plated copper, it provides excellent conductivity and corrosion resistance for dependable power distribution. With a substantial 155A current rating and a 1-pole configuration, the MPDB66201 facilitates efficient power splitting and splicing. It features a single input and one output connection point, utilizing stud connections for secure and consistent electrical interfaces. The stud dimensions are 3/8-16 x 1-5/16, with a stud-to-stud measurement of 1-5/16 inches, designed for straightforward and secure wiring. Mersen Power Distribution Blocks are integral for safely splicing cables, dividing primary power into multiple secondary circuits, and establishing required fixed junction tap-off points. The MPDB66201 is part of Mersen's intermediate size category (MPDB66 and MPDB67 series), offering a compact yet capable solution for power distribution needs. This series is available in various configurations, including aluminum and copper construction, and can accommodate single or dual conductor primary inputs with up to 30 secondary outputs. Specialty blocks are also available, featuring up to 7 primary inputs for more complex power distribution setups. The MPDB66201 specifically offers a 1-pole, 1-opening configuration with 3/8-16 x 1-5/16 stud dimensions for both line and load sides, as detailed in Mersen catalog data for the MPDB66200 series.

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.
