MPDB Series
Open-Style Power Distribution Blocks
THE NEXT GENERATION
POWER DISTRIBUTION BLOCK (PDB)
POWER DISTRIBUTION BLOCKS
Mersen power distribution blocks provide a safe and easy method of
splicing cables, splitting primary power into secondary circuits and
fulfilling requirements for fixed junction tap-o points. Unless noted
otherwise, all blocks 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 blocks are available allowing for up to 7 primary inputs. The
MPDB series is oered 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.
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 1-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.)
RATINGS:
Volts: 1000VAC/DC
Amps: 65 to 2260A based on NEC
table 310.15(B)(16) 75ºC ampacities
SCCR: 100kA with properly sized
fuse (See Mersen’s PDB SCCR
guide at ep.mersen.com or contact
Mersen Technical Services)
APPROVALS:
• UL Listed to subject 1953,
File E352417 unless noted
otherwise
• CSA Certified Class 6228 01

PART SELECTION NOTES
MPDBs in each size category come in one, two, and three pole configurations (ending in -1, -2, and -3
accordingly). Users also have the ability to field install additional poles, end barriers, and safety covers.

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: 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.
