Mersen MPDB Series 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-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.
• 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.
• Insulators are virtually unbreakable, made of glass-filled polycarbonate.
• 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.
• 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
• Direct panel mount
• UL94-V0
