Overview

NSI Industries NPDB-24-500-1 is a 100kA short circuit current rated power distribution block designed for high-current industrial applications. This unit features 2 x 500 MCM-4 AWG line terminals and 4 x 4/0-6 AWG load terminals, constructed from Valox Nylon 6/6 for superior dielectric strength and Lexan 500R Polycarbonate panels and covers for enhanced impact resistance and finger safety. The connector is made from high-conductivity 6061-T6 aluminum alloy with electro-tin plating for optimal current flow and corrosion resistance. The NPDB-24-500-1 is modular—each block can operate independently or combine with others to form multi-block sets. It is also DIN rail mountable with an integrated locking mechanism for secure installation and easy removal. The compact design and durable materials make it ideal for panelboard, switchgear, and industrial control panel applications where reliable power distribution and short-circuit protection are critical.
