Overview

The Mersen MPDB67511 is a high-capacity open-style Power Distribution Block (PDB) engineered for reliable electrical power distribution in industrial and commercial applications. This 1-pole PDB delivers a primary current rating of 270A (aluminum wire) and 350A (copper wire) at 1000V, making it suitable for high-power distribution systems. Constructed from tin-plated aluminum, it ensures excellent conductivity and corrosion resistance, extending service life in demanding environments. The MPDB67511 features two primary conductor openings per pole, accommodating wire sizes from 2/0 to #14 AWG, and provides two to six secondary openings (depending on configuration) for #2 to #14 AWG wire. This design allows for flexible cable splicing, splitting primary power into multiple secondary circuits, or serving as a fixed junction tap-off point. The box-to-box connection design simplifies installation and expansion within electrical panels, enclosures, or control systems. Typical applications include motor control centers, switchgear, industrial machinery, and renewable energy systems where high-current distribution and reliable connectivity are critical. Key specifications: - Voltage rating: 1000V - Current rating: 270A (Al) / 350A (Cu) - Material: Tin-plated aluminum - Poles: 1-Pole - Primary wire range: 2/0 to #14 AWG - Secondary wire range: #2 to #14 AWG - Connection type: Box to box - Series: MPDB67

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.
