This large-format block, part of the MPDB68 and MPDB69 series, features a tin-plated aluminum construction, ensuring reliable conductivity and durability. With a substantial voltage rating of 1000V and a primary current rating of 445A, it is engineered to handle demanding industrial applications. The MPDB69020 supports an adder current of 545A on one pole, providing flexibility for increased load capacity. Its connection type is Box to Box, facilitating straightforward integration into existing power distribution systems. This PDB is UL 1953 approved, meeting stringent safety and performance standards. Mersen power distribution blocks are essential for safely 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 and meet spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. The MPDB series offers options for single or dual conductor primary inputs and up to 30 secondary outputs, with specialty blocks available for up to 7 primary inputs. The MPDB69020, with its 1-pole configuration, is ideal for applications requiring efficient and safe power distribution. Its origin is Germany (DE), and its UNSPSC code is 39121410. This unit is designed for applications where high current and voltage handling are critical, offering a secure and compliant solution for power splitting and tap-off 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.
