Mersen MPDB67010 Adder Power Distribution Block 1000V

Product Description

The MERSEN MPDB67010 is an open-style adder power distribution block designed for splitting primary power into secondary circuits, cable splicing, and fixed junction tap-off points. The block features tin-plated aluminum conductors housed in a glass-filled polycarbonate body, and is rated for up to 1,000 volts AC or DC with a 310-amp adder capacity. It accepts conductors ranging from 2/0 AWG up to 350 kcmil and connects box to box, making it well suited for panel builds, switchgear, and industrial power distribution assemblies. Licensed electricians and panel builders are the typical installers for this component.

The MPDB67010 is used in commercial and industrial electrical installations where primary power must be distributed across multiple secondary circuits from a single point. Common applications include junction tap-off points in motor control centers, switchgear enclosures, and large panel boards. The adder configuration allows this block to be joined with compatible main distribution blocks to expand circuit capacity. It supports one to two conductors per opening and uses a screw-termination connection method for secure, reliable conductor retention.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or enclosure before installing or servicing this distribution block. Verify that conductor sizes are within the rated range of 2/0 AWG to 350 kcmil and that the assembly enclosure is rated for the application. Do not exceed the maximum operating temperature of 80 degrees C at the installation location.
