Overview

The NSI Industries NPDB-11-750-1 is a single-pole power distribution block from the BLOKS™ NPDB Series, engineered for robust electrical power distribution in industrial settings. This unit features a 100kA Short Circuit Current Rating (SCCR) when used with aluminum or copper conductors and appropriate fusing, ensuring safety in high-fault current scenarios. It is designed to accept one primary (line) conductor and one secondary (load) conductor, both within the 750 to 250 MCM wire range. The connector is constructed from high-conductivity 6061-T6 aluminum alloy with an electro-tin plating for superior conductivity and corrosion resistance. The base is made from Valox Nylon 6/6, and the finger-safe panels and cover are constructed from Lexan 500R Polycarbonate, providing IP20 protection per IEC60529. This design ensures operator safety by preventing accidental contact with live parts. The NPDB-11-750-1 is equipped with a built-in locking mechanism for secure mounting and quick release on a 35mm DIN rail, facilitating easy installation, removal, and reconfiguration. It supports multi-pole ganging to create larger distribution systems. The block has a maximum ampacity of 475A per pole and a voltage rating of 600V. Torque specifications for both primary and secondary connections are 442 in.lbf, and the required wire strip length is 1.732 inches for both. This power distribution block is UL1953 and UL1059 Listed. Applications include panelboards, switchgear, and industrial control systems requiring reliable and safe power distribution for high-current circuits.
