Mersen MPDB63160 Aluminum Distribution Block 1000V

Product Description

The MERSEN MPDB63160 is an open-style adder aluminum distribution block rated for up to 1000 volts AC/DC. It is designed to split a single power feed into multiple branch circuits within a panelboard, motor control center, or industrial enclosure. The connector body is tin plated aluminum housed in a glass-filled polycarbonate shell. Current ratings vary by conductor type: 65 amps for aluminum wire, 85 amps for copper wire, and 65 amps for diesel locomotive cable (DLO). Licensed electricians install this device during panel builds, service upgrades, and industrial wiring projects where circuit distribution is required at a single termination point.

The MPDB63160 fits residential, commercial, and light industrial applications where a single primary conductor must feed four secondary branch circuits from one block. Its adder-style design allows multiple blocks to be ganged together when additional circuits are needed. The primary and secondary openings both accept 14 to 4 AWG standard wire or 14 to 6 AWG DLO cable, making it suitable for a range of conductor sizes found in typical distribution and motor control applications.

Key Features

• 1000 volt AC/DC voltage rating supports a wide range of distribution applications
• One primary opening and four secondary openings per pole for 1-to-4 circuit splitting
• Accepts 14 to 4 AWG standard conductors and 14 to 6 AWG DLO cable on both primary and secondary
• Tin plated aluminum connectors resist oxidation and maintain reliable contact
• Glass-filled polycarbonate housing provides mechanical strength and electrical insulation
• Adder-style construction allows blocks to be ganged for expanded circuit count

Compatibility

Designed as an OEM-style replacement or new-installation distribution block for panelboards, motor control centers, and industrial enclosures requiring multi-circuit conductor termination.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before making any terminations. Use conductors within the specified AWG range to maintain current rating and ensure proper clamping force. When ganging multiple adder blocks, verify total load does not exceed the rating of the primary feed conductor.
