MPDB Series Open-Style Power Distribution Blocks Power distribution The Next Generation Power Distribution Block (PDB) Ratings: Volts: 000VAC/DC Amps: 65 to 2260A based on NEC table 30.5(B)(6) 75ºC ampacities Mersen power distribution provide a safe and easy method of splicing cables, splitting primary power into secondary circuits and fulfilling requirements for fixed junction tap-off points. Unless noted otherwise, all are UL and CSA approved while meeting spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code. PDB options include single or dual conductor primary inputs and up to 30 secondary outputs. Specialty are available allowing for up to 7 primary inputs. The MPDB series is offered in three size categories: miniature (MPDB62 and MPDB63 series), intermediate (MPDB66 and MPDB67 series), and large (MPDB68 and MPDB69 series), in both aluminum and copper. SCCR: 00kA with properly sized fuse (See Mersen s PDB SCCR guide at or contact Mersen Technical Services) Approvals: UL Listed to subject 953, File E35247 unless noted otherwise CSA Certified Class 6228 0 Features/Benefits: 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 -piece tin-plated. Many part numbers are rated to accept DLO-type fine-strand wire, allowing users to connect flexible conductors. (Continued on next page.) I4
MPDB Series Open-Style PDBs Power distribution Features/Benefits (Continued): 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: 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. Additional Specifications: Wire Type: Copper Blocks: 60/75ºC Solid/Stranded CU; Aluminum Blocks: 60/75/90ºC Solid/Stranded AL and CU Connector: Copper Blocks: Highly conductive tin-plated copper; Aluminum Blocks: Highly conductive tin-plated aluminum Insulating Material: Glass-filled polycarbonate with verified dielectric strength in excess of 2500V Flammability: UL94-V0 Mounting: Direct panel mount Environmental: RoHS compliant, Lead Free Part Selection Notes MPDBs in each size category come in one, two, and three pole configurations (ending in -, -2, and -3 accordingly). Users also have the ability to field install additional poles, end barriers, and safety covers. Safety Cover Optional, snap-on, hinged safety cover MPDBC6263 Miniature Series MPDBC6667 Intermediate Series MPDBC6869 Large Series End Barrier Snap-on to Adder pole to complete assembly MPDBE6263 Miniature Series MPDBE6667 Intermediate Series MPDBE6869 Large Series Adder Pole Snap-on Adder poles to fully assembled units to add additional poles in the field.
