The Next Generation Power Distribution Block (PDB). 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-off points. 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 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.

Mersen Power Distribution Block, Large Open Style, Series: MPDB, 600 VAC, 310 A, 3 Pole, 1 Primary Connections/Pole, 12 Secondary Connection/Pole, 6 AWG to 350 kcmil Wire, 100 kA Short Circuit, Polycarbonate, TiN Coated, Black, 7.89 in W x 5.7 in D x 3.55 in H Dimensions

• Aluminum connectors accept both aluminum or copper wire while copper connectors accept copper wire only and all 1-piece tin plated
• Connectors are all 1-piece tin-plated
• Insulators are virtually unbreakable, made of glass-filled polycarbonate
• See-through, hinged safety covers provide a greater degree of safety and shock resistance where required
• Hinged covers can be installed without tools
• 1 in through air and 2 in over surface between uninsulated live parts of opposite polarity meets requirements for feeder and branch circuit applications of UL508A
• 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
• 6 AWG to 350 kcmil Cu line, 14 to 4 AWG Cu load
